Due to their excellent wear resistance, heat resistance and other properties, PVD coatings are widely used in various industries. However, the defects of the coating make it impossible to demonstrate all of its advantages. If you want to solve the defects in PVD coating, you must know these defects, at least you should know – what...Continue Reading
