Characteristics of Zinc Plating with Alkaline Zinc Advantages
Zinc plating is a well-suited tool for protecting iron and steel products from corrosion. A metallurgical bond between zinc and steel allows zinc to corrode preferentially and thus protect the iron or steel against rusting.
The basic principle behind electroplating is the process of depositing a metal layer on a metal base using a direct current through an electrolyte solution. Zinc is one of the easiest metals to plate, giving good corrosion protection without using exotic chemicals. The finish can be polished to give a shiny luster almost as good as chromium.
Furthermore, zinc electroplating provides smoother, brighter surface in a shorter time than hot-dip galvanization in which steel parts are processed submerged in a bath of molten zinc. Alkaline zinc option produces a reliable, consistent coverage compared to acid zinc, with good brightness.
Zinc plating is extensively used by the automotive industry and for military applications. It is applied mainly to steel, but applicable to aluminum, copper, or brass with special pre-treatment. Colors are usually offered in clear (white), rainbow, green or black according to the type of post-plating treatments.
