Feature of Hard Chrome plating

Hard chromium plating is usually 10um-200um. Electroplated hard chromium plating has high hardness, wear resistance, corrosion resistance and can keep the surface bright for a long time. Hard chromium plating process is relatively simple, low cost, high profit. Hard chrome plating technology is often used to repair broken parts, including mold repair, hydraulic support repair, shaft repair.

When the coating of single-layer hard chromium plating reaches the required thickness, it has better corrosion resistance. However, when the thickness of chromium coating reaches more than 65μm, further increase of thickness will not further improve its corrosion resistance. Generally speaking, the plating time has a great influence on the thickness of the hard chromium layer, and the choice of plating time depends on the main salt concentration of the plating solution, temperature, current and other process conditions.

Our Hard Chrome Plating Machine

In the actual plating process, in order to accurately control the thickness of the chromium plating layer and improve the uniformity of the coating of the outer round chromium plated parts, the cylindrical plating anode is often used, and the alloy steel parts are regularly turned over and changed during the plating process to ensure the uniform and detailed hard chromium plated layer
