Evaluation of Interfacial Fatigue Strength of Hard Coating by Using Repeated Laser Shock Adhesion Test

This study aims to evaluate the adhesion strength and durability of hard coatings in a non-contact manner by using Laser Shock Adhesion Test (LaSAT). Both heat-treated and as-plated (non-heat-treated) Ni-P coatings deposited on carbon steel substrate by electroless plating method were prepared as specimens for this study. LaSAT uses strong elastic waves induced by pulsed laser irradiation in order to apply tensile stress to the coating/substrate...
