Corrosion is the process of degradation or failure of a material resulting from a chemical reaction between the material and its surrounding environment. It is an indispensible research area in material science and engineering, because corrosion resistance characterizes the stability or durability of a material, which is one of the most important material performances in application. Compared w...

Cavitation is a physical process that produces complex effects on the machines and components working in conditions where it acts. One effect materials-mass loss by corrosion–erosion when are introduced into fluids under cavitation. The analysis of damages produced cavitation generally performed using different destructive non-destructive experimental techniques. Most studies materials’ behavio...

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 ca...
