Tungsten alloy electroplating is a kind of anticorrosion and wear resistant technology applied to surface treatment of mechanical equipment parts. The main properties of this technology, such as wear and corrosion resistance, are superior to that of chrome plating.

Tungsten alloy electroplating is environmentally friendly, energy saving and high in material utilization rate so that it is considered as an alternative process of chromium plating.

 

Oil field equipment "corrosion" and "wear" is known as the two major problems in the world. There are about 29,200 wells have different degrees of corrosion and wear in China, and it’s getting worse with the number of developing years and service life of equipment increasing. In addition, the import of high sulfur crude oil has increased considerably, and the corrosion problem of refining equipment has become increasingly prominent. Even more frightening is that due to corrosion and wear, the adverse effects on the safety and stability of the equipment will become more serious.

 

 

Tungsten alloy electroplating process solves two major problems of equipment corrosion and wear at one stroke. The application of tungsten alloy electroplating technology in petroleum machinery industry can solve the problem of pollution caused by chromium plating, and improve the performance of all kinds of key parts of the products in Chinese petroleum machinery manufacturing industry, which bring change to the whole petroleum machinery manufacturing industry, and promote the overall upgrading of the industrial chain.

 

The hardness and wear resistance of tungsten alloy is equal to chromium electroplating, but tungsten alloy has acid and alkali resistance, low production cost, and can configure electroplating solution according to the specific situation of oil downhole operation, implement the corresponding electroplating process, and meet the requirement. Now, in the same environment, tungsten alloy electroplating equipment has several times longer of service life

 

The properties of tungsten alloy plating is so superior because the tungsten alloy plating coating is obtained after the new alloys, which has good wear resistance, good acid and alkali resistance, salt fog resistance, and excellent binding force between oxidation resistance and substrate materials. Tungsten alloy electroplating process is a traditional processing technology, also called tungsten alloy chromium plating technology. It is widely used in metal corrosion protection and wear prevention, to prolong the service life.
