镀层中的应力直接影响镀件的质量,在镀件中由于应力的存在,会导致工件的变形,当应力达到一定大小时会引起镀层表面的开裂和镀层与基件粘着不良等缺陷。这种现象的产生会大大降低镀件的耐蚀性,甚至会造成工件失去使用价值。为了测定镀层的应力,有人曾经作过一些定性的尝试(内田, The stress in the coating directly affects the quality of the plating. Due to the existence of the stress in the plating, the deformation of the workpiece will be caused. When the stress reaches a certain size, the surface of the plating will crack, defects such as the coating and the base are poorly adhered. This phenomenon will greatly reduce the corrosion resistance of plating, and even cause the workpiece to lose its value. In order to determine the coating stress, some people have made some qualitative attempts (Uchida,
