ABSTRACT An automotive sealed chain consisting of an elastomeric seal between chain plates prevents the entry of external contaminants. But, the presence of a seal induces high transmission loss due to the frictional force. In the present study, a comparative transmission loss test between two ANSI-B29.1 520 series sealed chains of equal geometric dimensions (5/8” pitch) was carried out. The tests revealed a significant difference of 38% in their transmission losses between the chains. To understand these observed differences in the chain performance, the material analysis of the seals (nitrile butadiene rubber) was performed, which showed a significant difference in their composition. The increased seal hardness due to difference in chemical properties resulted in a 21% increase in friction coefficient between the seal and the plates. The seal thickness reduction, the effect of lubricant, and the difference in the frictional forces between chains yielded differences in the transmission losses. GRAPHICAL ABSTRACT

ABSTRACT The purpose of this paper was to understand how axial cylinder distortions influence the tribological performance of piston ring. The current model contains the effects of axial distortions and ring conformability under mixed to hydrodynamic regimes of lubrication through computational fluid dynamics predictions. The axial cylinder profiles were modelled using series of sinusoidal waves. The effect of axial distortions on ring wear rate was determined using the Archard’s model. The ring friction and minimum lubricant film were predicted for low and high combustion pressures near to top dead centre. The study shows that, when the maximum combustion pressure rises, the different wear identities affect the operation of the ring friction much more limited, while the number of sine waves are more pronounced. Finally, it is proved that, even the increase of oil film thickness, it does not presuppose the reduction of friction when it comes to shaping the surface of the cylinder liner. GRAPHICAL ABSTRACT

ABSTRACT In the present work, Cu alloyed ductile iron was isothermally treated at five different temperatures (280°C, 300°C, 320°C, 350°C, and 380°C) for 1 h to obtain an ausferrite microstructure composing a very fine ferrite phase and carbon enriched austenite. Microstructural characteristics exhibited a high ultimate tensile strength of 950–1600 MPa of ADI comparable to or even stronger than forged steels. The bulk hardness was 460–288 HV10, higher than pearlite, but lower than pure martensitic. The tribological behaviour of ADI was investigated using a 10 mm pin diameter during sliding. Its friction coefficient decreased almost by half as compared with ductile iron due to its ausferritic morphology and carbon enrichment. Under oxidative and adhesive conditions, an austempered microstructure with very fine ferrite and high carbon austenite is most wear-resistant due to its adequate strength, toughness, and lubricative behaviour. Wear resistance of ADIs can be improved through tailoring microstructure through austempering. GRAPHICAL ABSTRACT

ABSTRACT The present work has been performed to understand the erosion of hydro-turbine steels due to the impact of suspended sediment using a high-speed pot tester. Experiments have been performed at five different velocities of 13–32 m/s and four different mean particle sizes of 143–362.5 μm for the sand concentration of 3000 ppm. The orientation angle of the wear specimens was varied from 15° to 90° using an angular disc. Correlations for cutting and deformation have been developed to estimate the total erosion wear. The erosion mechanisms are also studied by scanning electron micrographic analysis of the eroded surface. The velocity exponent for CA6NM steel is observed as 2.07 and 2.14 for cutting and deformation wear rates, respectively, significantly higher than that observed at low velocity ranges. The correlation developed may be further used for numerical estimation of erosion. GRAPHICAL ABSTRACT

ABSTRACT The precise control of tungsten content of electrodeposited nickel–tungsten (NiW) on brass substrate was achieved by applying a well-designed pulse reverse current waveform. A crack-free, uniform and, mirror-like finish surface was obtained by using a novel derivative of propargyl compound, propargyl-oxo-propane-2,3-dihydroxy, as a brightener and grain refiner into the electrodeposition bath. This study indicates that the electrodeposited nickel–tungsten alloys with an optimum tungsten content (32 wt%) possesses outstanding mechanical and, wear performance, also with very low friction of coefficient of 0.2.

ABSTRACT The tribological characteristics of Ti alloys containing beta stabilisers such as Mo, Nb, Ta, Zr, and Sn have seldom been explored despite their applicability for metallic biomaterials requiring good wear and surface degradation resistance. Using sliding wear contact, the influence of these alloying components on Ti-Mo biomedical alloys in simulated physiological fluid was examined. Microalloying influences microstructure, hardness, and wear. Nb-microalloyed samples with metastable -phase increased anti-wear and frictional resistance while keeping frictional resistance. Orthorhombic α′′phase-rich samples were the least wear resistance. The findings contribute to a better understanding of the interaction between Ti-based biomaterials' micro-alloying and their tribological properties. The stabilised TiMo (Nb,Ta, Zr, or Sn) alloys outperformed CP-Ti, the original Ti92Mo8, and the regularly used biomedical Ti6Al-4V alloys in terms of corrosion resistance. This indicates that alloying tuning may be used to enhance biomedical prosthesis and increase the service life of bio-implants and components. GRAPHICAL ABSTRACT

ABSTRACT This work studied the sliding wear performance of TiAl-based nitride coatings synthesized on austempered ductile iron (ADI) by cathodic arc deposition (CAD) and plasma-based ion implantation and deposition (PBIID). Monolayer CAD TiAlN films and bilayer CAD and PBIID TiAl/TiAlN films deposited on an experimental device were analyzed and benchmarked against a commercial bilayer CAD film. Sliding wear was evaluated in a pin–on–disc tribometer. Two test conditions were employed, one intended to prevent damage (low load, short distance) and another intended to promote damage (higher load, longer distance). Regarding low load tests, all coated samples showed friction coefficients of 0.40–0.45 and negligible wear. Regarding high load tests, all coated variants exhibited lower or equal disc and pin wear rates with respect to uncoated ADI. In addition, coated samples displayed steady-state friction coefficients between 0.2 and 0.6 while uncoated ADI steady-state coefficients between 0.6 and 0.85. GRAPHICAL ABSTRACT

ABSTRACT Hydrodynamic turbine and slurry pump components are frequently influenced by severe wear due to the impact of solid particles present in the water. A WC-based coatings deposited by thermal spray techniques is known for the protection against slurry erosion. In the present work, WC-Cr3C2-Ni powder was sprayed on a turbine steel substrate using high-velocity oxy-fuel (HVOF) and atmospheric plasma spray (APS) techniques. Microstructural and phase constitutions of as-sprayed coatings were examined. The effect of speed, slurry concentration and particle size on slurry erosion resistances of both coatings and substrate materials was comparatively studied in a slurry pot erosion tester. The results exhibit that the HVOF coating has better properties in terms of density, micro-hardness and slurry erosion resistance than those of APS coating. The improvement in slurry erosion resistance of bare turbine steel by using APS and HVOF coatings is approximately 37% and 62%, respectively. GRAPHICAL ABSTRACT

ABSTRACT Wear during running-in of rolling contact occurs at the surface asperities level and cannot be assessed using a conventional mass loss technique due to the very small changes. The purpose of this paper is to propose an in-situ wear volume measurement using the BAC technique. The experimental work is conducted in-situ and a fixed datum is set as a reference to avoid measurement errors. The wear volume measurement using a proposed BAC technique is in good agreement with the asperities profile-based technique with a small error of 1.67%. The relocation at 90% of BAC is unnecessary as it causes a measurement error of 4.67%. Therefore, the assumption that no change in the asperity valleys beyond 90% of BAC is inaccurate and may lead to error in the wear volume assessment. This study provides a validation of the BAC technique that has been used extensively in wear volume measurement. GRAPHICAL ABSTRACT
