Steel Hard Chrome Plating Machine 0.2um Coating Thickness

1. Technological process of production

Blank inspection → racking → chemical degreasing → water washing → electrolytic degreasing → water washing → Anodizing (in chromium plating bath) → chromium electroplating → recycling → water washing → put down → water washing → drying → inspection → hydrogen removal → packaging

2. Main process introduction

Chemical degreasing:remove the oil on the surface of products

Electrolytic degreasing: further remove the oil on the surface of products to ensure the binding force of the coating .

Pickling: remove the oxide from the surface of products and activate the product surface .

Water rinsing: clean the product thoroughly after the tank to avoid mutual contamination of the tank.

Anodizing:Let the surface of the steel substrate be in an activated state and produce micro rough surfaces, and then proceed with plating. Ensure obtaining a hard chromium coating with good adhesion.

Chrome plating: the product is coated with a uniform coating.

Hydrogen removal:reduce the brittleness of chromium plating and clean the hydrogen embrittlement of the base metal.
