Effect of Chemical Composition and Microstructure of Zn and Al-based Coatings on Electrochemical Response in Corrosive Environments

Hot formed steels are witnessing an increasing use in safety critical and structural parts for automobiles due to their high strength, light weight and absence of springback, due to which understanding the corrosion behaviour of coated products for hot forming is crucial to increase their stronghold in Body-In-White (BIW) applications for...

Stress gradients in CrN coatings

Stress in hard films is the net sum of tensile stress generated at the grain boundaries, compressive stress due to ion peening, and thermal stress due to the difference in thermal expansion of the coating and substrate. The tensile part due to grain boundaries is thickness dependent. The other two contributions are not thickness dependent....
