Four Coating Methods of Tungsten Disulfide

Tungsten disulfide paste picture

Tungsten disulfide (WS2) is a silver-gray lubricant powder, with an extreme low friction (COF: 0.03) and excellent thermal stability and pressure resistance. When coated on a substrate, it forms a 0.5 micron thick layer of WS2 coating, which reduces the friction and increases thermal stability and pressure resistance of it. Here are   four coating methods to apply WS2 powder:

The manufacturing of tungsten carbide die and repairing of old mold are inseparable from mechanical grinding. Relatively speaking, the grinding process is more complicated, which including rough grinding, fine grinding, fine grinding and polishing. Under normal production conditions, the die wear is not very serious. So, the grinding usually includes fine grinding, fine grinding and polishing.

Tungsten carbide is a composite of refractory metal compounds and bonded metal, of which the most widely used material is refractory metal carbides. Tungsten carbide is the main component, followed by titanium carbide, niobium carbide and its solid solution. Common characteristics of these carbides are high melting point, high hardness, good chemical stability, good thermal stability and small dissolution with the interaction of bonded metal at normal temperature.

Gas Recovery Cycle System for Tungsten Alloy Sintering

gas recovery cycle system for tungsten alloy sintering image

Researchers found that the atmosphere around tungsten alloy billets plays a key and decisive role in sintering quality during sintering. In particular, when tungsten alloys are sintered in large quantities, as tungsten alloys contain alloy additives, a large number of impurities are discharged during sintering, the greater the amount of furnace loading, the greater the impurity of the discharge and the worsening of the sintering atmosphere. The protective gas can take away a large amount of impurities produced in the sintering process and ensure the sintering quality. Therefore, on the one hand, the need for hydrogen excess to meet the requirements of sintering, on the one hand, need to reduce the amount of hydrogen to reduce the cost, which is a dilemma.
