For the purpose of establishing a quantitative method of the adhesion strength of metal plating, scratch examination which is applying in ceramic coating was conducted and performed the comparison with the adhesion test of the ISO 2819 and Japanese Industrial Standards about the effectiveness. With diamond indenter having tip a radius of 0.2, 0.4, and 0.8 mm, scratched at a plating surface while gradually increasing load on the indenter and a load to generate a crack near the scratch was checked whether producing significant difference. In addition, the influence of material properties of the plating including crystal structure and the internal stress gave to the adhesion strength was examined. As a result, the adhesion strength decreased with the growth of the crystal, and it was revealed that the stress in the plating did not influence the adhesion strength.
