The appearance inspection of the electroplating layer of metal parts is the most basic and most commonly used inspection method. Plated parts with unqualified appearance do not need to be tested for other items.
Visual observation is used during inspection. According to appearance, plated parts can be divided into three categories: qualified, defective and scrap.
Poor appearance includes pinholes, pitting, tumors, peeling, blistering, falling off, yin and yang sides, spots, burns, shadows, dendritic and spongy sedimentary layers, and parts that should be plated but are not defect.
