The quality of electroplating is mainly measured by its corrosion resistance, followed by its appearance. Corrosion resistance is to imitate the working environment of the product, set it to test conditions, and subject it to corrosion tests. The quality of plating products is controlled from the following aspects:
The surface of the product is not allowed to have local non-plating, scorch, rough, gray, peeling, crusting, and obvious streaks. It is not allowed to have pinhole pits, black plating slag, loose passivation film, cracking, shedding and serious Passivation traces.
The working life of a fastener in a corrosive atmosphere is directly proportional to the thickness of its coating. The general recommended economic plating thickness is 0.00015 to 0.0005 in (4 to 12 um).
Hot-dip galvanizing: The standard average thickness is 54 um (claim diameter ≤ 3/8 is 43 um), and the minimum thickness is 43 um (or nickname ≤ 3/8 is 37 um).
