- Sanjack has the most advanced fourth-generation nickel based tungsten plating technology in China.
- Sanjack is has 7 advanced tungsten plating production lines in China.
- Sanjack can produce 10,000 tons of various anti-corrosion tubing annually, and plate the ID of 2,000 downhole pump barrels.
Due to the strong carcinogenicity and severe environmental of hexavalent chromium ions, the use of chrome plating technology in China has been gradually limited, and some products have been limited by the two directives, WEEE and ROHS from EU. Therefore, the new environmentally friendly substitution of chromium technology R & D draws more and more attention. And as a new substitution of chromium technology, tungsten alloy plating process, due to its special structure as well as good wear resistance and corrosion resistance, has been gradually focused on by people.
Sanjack is endowed with 7 advanced tungsten plating production lines in China. These environmentally friendly production lines, with high degree of automation, can produce 10,000 tons of various anti-corrosion tubing annually, and plate the ID of 2,000 downhole pump barrels.
Composite-plating is widely used in tubing, sucker rod, sucker rod pump, engine components supplies. Based on the advanced nickel-based technology, Sanjack composite plated products take the lead in China and have the following advantages: anti-corrosion, anti-abrasion, rare fouling, strong adhesive.
Key Feature
- On plating appearance, no blister or falling happens through the grind & saw test as well as thermal shock test.
- Hardness＞900HV after heat treatment
- Resistance to acid, alkali, chloride ions
- Plating appearance adherence kept at 300℃
- Plating thickness: 30μm-50μm
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.
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.
Wear Resistance Comparison
1.Comparison of Nickel-Tungsten Composite Plating and Chromium Plating on Wear Resistance
We verify the wear resistance of Nickel-Tungsten Composite Plating and Chromium Plating through experiments. We prepared two kinds of coating tests, under the specific experimental conditions for friction, to verify the wear resistance.
Test Data for Chrome-plated Specimen Wear Resistance
Test Data for Nickel-Tungsten Composite Plating Block on Wear-resistance
Experimental Data and Results
| Type of plating | Chrome layer | Nickel tungsten composite |
| Coefficient of friction | 0.54 | 0.44 |
| Scratch depth (um) | 1.86 | 0.59 |
| Vickers hardness HV0.2 | 928-950 | 970-1026 |
| Conclusion | Nickel-tungsten composite plating constitutes at least 3 times better than chrome-plated layer for wear resistance. | |
