Sanjack: Your Premier Choice Of Composite Tungsten Plated Tubing & Casing
Sanjack take the most advanced fourth-generation nickel based tungsten plating technology and built 7 advanced tungsten plating production lines.
Sanjack: Your Best China Composite Tungsten Plated Tubing&Casing Manufacturer and Supplier
After two years of intensive research and development, Sanjack successfully developed a new type of composite plating technology, which is widely applied in tubing and polished rod surface treatment. At present, related products have realized mass production.
Composite plating is based on electroplating and electroless plating , adding nonsoluble particles (such as ceramic particles) into the bath, so that particles can be deposited with the plating. As a result, the plating has the characteristic of both the metal plating and the particles.
Sanjack: Your Best Place To Custom Composite Tungsten Plated Tubing & Casing In China
We verify the wear resistance of Nickel-Tungsten Composite Plating and Tungsten Plating through experiments. We prepared two kinds of coating tests, under the following experimental conditions for friction, to verify the wear resistance.
Experimental Conditions
| Effective Stroke Length | 100mm |
| Speed for Abrasion | 100 times /min |
| Temperature of Service | Room Temperature |
| Load Pressure | 400N |
| Amount of Test | 400 Thousand |
Experimental results are as follows:
