Scratch Adhesion and Wear Failure Characteristics of PVD multilayer CrTi/CrTiN Thin Film Ceramic Coating Deposited on AA7075-T6 Aerospace Alloy

Scratch Adhesion and Wear Failure Characteristics of PVD multilayer CrTi/CrTiN Thin Film Ceramic Coating Deposited on AA7075-T6 Aerospace Alloy

This study highlights the scratch adhesion failure characterization and tribo-mechanical properties of physical vapor deposited (Cr, Ti) N coating on AA7075-T6 by using magnetron-sputtering technique. The surface morphology, microstructure and chemical composition of CrTi/CrTiN fim were inspected b...
