Wear and Corrosion Resistance of CrYN Coating in Artificial Seawater

In this study, CrYN coatings were prepared using multi-arc ion plating at various substrate bias voltages (−50 V, −100 −150 and −200 V). X-ray diffractometry scanning electron microscopy used to characterize the composition microstructure of coatings. An electrochemical workstation a ball-on-disk tribometer investigate their corrosion friction behavior. The results show that grain refinement can be achieved through addition yttrium (Y) surfaces under different have varying smoothness compactness. It was shown V relatively smooth dense in structure, corresponding Y content 2.83 at.%; highest potential low self-corrosion current, equating superior resistance. Additionally, coefficients deposited less than 0.2. Therefore, had minimum wear rate due its resistance, friction.
