The tribo-corrosion performance of laser powder bed fusion WC/W2C reinforced stainless steel in different pH value solution
Laser powder bed fusion (LPBF) 420 stainless steel reinforced with 5 wt% WC/W2C exhibit notable corrosion and wear resistance. However, the stability of the reinforced particles and stainless steel shows an inverse relationship with fluctuating pH levels. This research investigates the corrosion resistance and tribo-corrosion performance of WC/W2C particles strengthened LPBF 420 stainless steel composites in acidic, neutral, and alkaline environments. The open circuit potential (OCP) in acidic environment is −0.48 VSCE, which is 0.34 VSCE and 0.05 VSCE lower than that observed in neutral and alkaline solutions, respectively. The maximum depth recorded after tribo-corrosion testing follows the trend of acidic (5 μm) > neutral (3 μm) > alkaline (0.6 μm), indicating the worst corrosion resistance and tribo-corrosion performance in acidic environments. The WC/W2C demonstrates dissolution in alkaline conditions, leading to diminished corrosion resistance compared to neutral solutions. However, the friction products formed in alkaline environments contribute to an enhanced coefficient of friction (COF) value and tribo-corrosion resistance when compared to neutral solutions.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
