Characteristics of New Coatings for Electroless Nickel Plating

Characteristics of technical commodities with electroless nickel plating of new coatings.

The progress of many things is closely related to our daily life. It is advantageous for everyone to know more about those foods. Electroless nickel plating is a surface treatment process, which makes the surface of the product more complete and also brings protective products. With the rapid progress of social development, the technology of galvanizing has also been greatly changed, and the technology has been improved. Let's understand the characteristics of the new coating technical products and carry out a detailed introduction.

1. Strength. The strength of the electroless nickel plating layer is much higher than that of the electroplated nickel layer, and it is more resistant to wear. The strength of the electroless nickel plating layer is usually HV300 to 500. If the heat treatment method is used, the strength of the electroless nickel plating layer can be improved. When heated at 400 degrees for 1 hour, the strength value can reach HV1000. Moderately reducing the heat treatment process temperature and increasing the treatment time can also improve the hardness value.

2. Magnetic properties, the magnetic properties of electroless nickel plating layer are affected by phosphorus content and heat treatment temperature. Coatings with phosphorus content exceeding 8 percent are weakly magnetic. When phosphorus content is more than 11 percent, there is no magnetic property at all. , The coating with phosphorus content less than 8% has magnetic properties, but its magnetic properties are smaller than that of electroplated nickel layers, and the magnetic properties are significantly improved after heat treatment.

3. Resistivity, the resistivity of the electroless nickel plating layer is related to the phosphorus content, the more phosphorus content, the greater the internal resistance of the product.
