Factory Direct Supply Aisi 5140 Alloy Steel Chrome Plating Process - China

The chrome plating process for AISI 5140 alloy steel primarily involves the following steps:

1 - Surface Pretreatment

- **Cleaning**: Removes impurities such as oil and rust from the workpiece surface using chemical cleaners or mechanical methods.

- **Activation**: Electrochemically activates the workpiece surface to improve the adhesion of the coating.

2 - Chrome Plating Method

- **Brush Plating**: Deposits a chromium layer on AISI 5140 steel surfaces using brush plating.

Brush plating is a portable surface modification method that allows for adjustable coating thickness and excellent deposition quality.

Brush plating parameters include: electrocleaning (+10V, 60 seconds), strong activation (-10V, 30 seconds), weak activation (-18V, 30 seconds), and brush plating (+10V, 10 minutes).

- **Double Glow Plasma Surface Alloying (DGPSA): A chromium coating is synthesized on AISI 5140 alloy steel surfaces using DGPSA technology.

The chromium coating formed by this method consists of a deposited layer, a diffusion layer, and an impact layer.

This process produces a high-quality chromium coating on AISI 5140 alloy steel, enhancing its wear and corrosion resistance.
