This paper investigates the effect of SAE grade 20W50 engine oil as a lubricant on the wear behaviour of chromium nitride (CrN) coating deposited by PVD process at higher loads and speeds by pin on disc tribometer. The specific wear rate ranges from 9.82 × 10-5 to 2.87 × 10-5 mm3/Nm in dry condition whereas in lubricated condition 0.97 × 10-5 to 0.19 × 10-5 mm3/Nm. Successive increase of speed and load rises the temperature of wear track from 65°C to 178°C in dry condition while 34°C to 40°C in lubricated conditions results to decrease in friction coefficient, which has immense influence on the wear resistance of coating. The wear mechanism of the coatings was analysed by SEM and EDS and found deformation, cracks and, nitride particle pull-out, built up edge formation, erosion and adhesive wear coupled with oxidation wear. The highlights of the paper are: 1) tribology of CrN coating against cylinder liner material as counter face summarised; 2) research has practical applications for piston ring with the influence of engine oil; 3) temperature ranges from 65°C to 178°C in dry and 34°C to 39°C in lubrication during wear test; 4) the wear mechanism is combination of three body abrasion, metal transfer and oxidation.

As a pre-study for highly oriented collagen coatings on implants (with irregular surfaces and shapes), the Langmuir-Blodgett (LB) technology, a low-cost and straightforward approach, was pioneered. The effects of physicochemical (hydrophilic/hydrophobic) patterns and 3D-mechanical barriers present on substrate surfaces are studied in terms of the dynamics of collagen flow during LB film deposition and the formation of highly oriented coatings. Due to the large internal cohesion of collagen films, only large 3D-obstacles deflect the flow of collagen and lead to film rupture, suggesting that objects (screw-threaded dental implants) with small topographic features should be easily and evenly coatable. Moreover, hydrophilic/hydrophobic/collagen patterned substrate surfaces were fabricated, by partly removing coated collagen. These substrates are outstanding for timely studies that need identical conditions but different surface properties side by side. Crystallisation of barium oxalate was carried out as a proof-of-principle.

This paper investigates the tribological properties of Mg-6Al alloy-based nanocomposites reinforced with nano-size alumina nanoparticles. Dry sliding wear tests were performed in the pin-on-disc arrangement opposite to a D2 steel counterface under various sliding velocities 0.8-2.0 m/s with 10 N, 30 N and 60 N normal loads at room temperatures. The variations in volumetric wear rate and friction coefficient with the sliding distances 300 m for different normal loads and sliding velocities were analysed. The worn pins and wear debris were then examined to reveal its wear features using a field emission scanning electron microscopy. The outcomes of the study reveal that there is a gradual decrease in wear rates with sliding speeds under all load conditions. The values of friction coefficient for nanocomposites varies between 0.15-0.23 and reaches minimums at 2.0 m/s under 10 N and 1.8 m/s under 30 N and 60 N load.

The electrochemical characteristics of the RE-M-B magnetic powder bonded with polymeric biomaterial have been presented. It has been proven that the ratio of the binder to the magnetic powder effect on the surface roughness of the final magnetic material. With the increase of surface roughness also increases in the actual area of the metallic material contact with an aggressive environment - increased surface roughness promotes penetration of the corrosion medium into the material and consequently is favourable for the corrosive destruction. In the article the results of roughness measurements, vibratory magnetometer, microscopic analysis (2D) and corrosion tests in two corrosive environments: 0.5 M solution of sulphate acidified to pH = 2 and Ringer's solution (pH = 6) have been presented. All tests had been carried out on magnetic composite based on Nd-(Fe, Co)-B magnetic powder bonded with polymeric biomaterial.

The tribological behaviour of 60 wt. % bronze filled PTFE sliding against AISI 420 stainless steel in ambient air, distilled water and sea water was investigated. The experiments were conducted on a pin on disc tribometer at room temperature at a normal load of 10N. The bronze filled PTFE showed superior tribological performance in sea water as compared to distilled water and dry sliding. The lowest average coefficient of friction (0.045) and lowest specific wear rate (1.10 × 10‒5mm3/Nm) were observed under sea water environment. Surface morphological and surface analytical studies were conducted using optical microscopy, SEM, EDS and 3D surface profilometer to reveal wear mechanisms. From profilometric traces of counterface, it was observed that there was no increase in the surface roughness of the counterface after sliding against bronze filled PTFE in sea water and hence indirect corrosive wear is not the dominant wear mechanism.

The demand for aluminium-based metal matrix composites is growing in aerospace and automotive industries because of its good corrosion resistance and high strength to weight ratio. The present work focuses on tribological characteristics of stir cast hybrid composites synthesised with AA6063, Boron carbide and zirconium silicate. Composite specimens were prepared with three percentages of reinforcement materials by weight, i.e., 3%, 6% and 9%, and the matrix material at 88%. Tribological experiments were conducted on the specimens with a pin-on-disc tribometer, using L9 orthogonal array experiments with various parameters including load, speed and time. SEM and optical micrographs were employed to investigate the mode of wear mechanism on worn out surfaces of the specimens. The investigation has confirmed that the hybrid composite synthesised with 3% boron carbide and 9% zirconium silicate has shown an enhanced wear resistance with a lower coefficient of friction as compared to the other composites.

Present paper discusses the effect of graphite powder on the wear and friction properties of aluminium melt. The aluminium graphite composite was fabricated using the stir casting technique. Three different amounts of graphite particle with 2 wt. %, 4 wt. % and 6 wt. % are used for the fabrication of the composite. Pin on disc experiments were performed as per ASTM-G99 between aluminium graphite (Al-Gr) composite and mild steel tribopair. Scanning electron microscope images for the worn Al-Gr composite were obtained to study the wear of the composite. It is observed that graphite particles help in reducing the wear and friction coefficient of the aluminium.

The effect of milled fly ash on the tribological response of brake friction composites is studied. Two specimens were developed using raw fly ash (RFA) and milled fly ash (MFA) and tested for the friction and wear performance at different loads (50-100 N) with sliding velocities varying from 1.7 to 3.3 m/s. It was observed that the spherically shaped RFA particles transformed into rough and uneven shaped particles after ball milling. The particle size range was found to be 22.05-206.19 μm before milling which reduced to 3.02-40.64 μm after milling while the specific surface area increased from 138.23 m2/m3 to 1008.98 m2/m3. The μavg of RFA specimen varied from 0.23 to 0.57 during braking conditions. However, the MFA specimen experienced approximately a constant value of 0.52 at 50 N with the increase in sliding velocities, whereas slight variation was observed at higher loads. The results showed that the mechanical milling enhances the stability and consistency of friction coefficient as compared to raw fly ash.

In this study, epoxy and SU-8 resin along with its composites was coated over bearing steel. The graphite, talc and base oil were used to fabricate the composites using spin-coater. The tribological and surface characterisation tests were performed on both type of polymer and its composite using ball-on-disk setup, optical microscope, 3D optical profilometer, and goniometer, respectively. From the results, it can be seen that epoxy and its composites polymer showed lower coefficient of friction (~0.16), high wear resistance properties (> 102 times), improvement in mechanical properties (elastic modulus and hardness) (~3-4 times) and better hydrophobic nature as compared to SU-8 polymer (~34%) and its composites. Furthermore, a neural network model was developed to determine the influential parameters on specific wear rate and coefficient of friction.

The impact of micro and nano silicon carbide (SiC) filler addition on thermo-mechanical behaviour and erosion wear is investigated. Woven glass-vinyl ester composites are developed, filled with 5 wt% and 10 wt% of micro and nano SiC fillers, respectively. Filler less composites are also prepared for comparative study. Thermo-mechanical characterisation of composites is done as per ASTM standards. Erosion wear test is performed on composites for various angles of impact (30°, 45°, 60°, 75° and 90°) and impact velocities (30, 55 and 80 m/s). Silica sand as an erodent particle with size of 300, 450 and 600 μm is used for the experimental work. Taguchi statistical method is used for design of experiments to optimise the process parameters. Results reflect that nanocomposites filled with 10 wt% of nano SiC filler performed best amongst the whole lot. VIKOR method is also implemented for fabricated composites to optimise their performance.
