Evaluation of adhesion durability of Ni–P coating using repeated Laser Shock Adhesion Test

This study aims to evaluate the adhesion strength and durability of NiP coatings in a non-contact manner using the Laser Shock Adhesion Test (LaSAT). A hard coating of electroless NiP deposited on carbon steel substrate (SKD11) was prepared, and the effect of post heat treatment on adhesion was comprehensively investigated in this study. With the LaSAT, strong elastic waves induced by pulsed YAG laser irradiation applies tensile stress to the...
