Effect of surface nanocrystallization on corrosion behaviour of coated steel in chloride solution
International Journal of Electrochemical Science, 2018 A nanocrystalline (NC) layer was fabricated on the surface of the low-alloy steel 15CrMo using high-energy shot peening. Two kinds of conversion coatings including the chemical conversion coating and electrochemical conversion coating were separately ...

Advanced Engineering Materials, EarlyView.Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...
