The properties of hard chrome coating include: high hardness and corrosion resistance, low friction coefficient and low adhesion tendency.
This coating is widely used in automotive, aerospace, mining and general engineering industries for applications such as internal combustion engine parts, hydraulic jacks, plastic injection molds, restoration of worn and worn parts, as well as undersized parts, rollers and machine tools. Instruments are used.
In the Second World War, hard chrome coating was used to prevent the wear of the barrel of weapons.
Hard Chrome Coating Thickness:
It is suitable for the application of hard chrome coating of different thickness. For example, in plastic injection molds, the thickness is around 10 to 20 microns, while in parts that are subjected to wear, the coating thickness is more than 100 microns.
Metals where chrome plating can be performed on:
- فولاد کربن استیل سخت کاری شده و نشده
- چدن
- استیل ضد زنگ
- فولادهای ابزاری
- فولادهای هوافضا
- فلزات غیر آهنی نظیر مس، برنج، آلومینیوم، مونل، روی
Principles of Chrome Plating Design Hard:
For the basic design and engineering of the hard chrome plating line, the area of the largest piece that needs plating must be determined first. Then the production rate is determined. In other words, the number of pieces that should be plated in each cycle should be specified.
According to the need of production and determining the placement of the piece vertically or horizontally in the tub, the following are determined:
2- The number of anodes required
3- The dimensions of the copper belts required
4- The capacity of the rectifier required
5- The capacity of the fan and the dimensions of the hood required
