Tungsten carbide coating is a coating prepared on the surface of the substrate, the main component of which is tungsten carbide. Tungsten carbide is a very hard ceramic material, with high melting point, high hardness, high wear resistance, high corrosion resistance and other excellent properties. The hardness, wear resistance, corrosion resistance and high temperature resistance of metal surface can be improved by using tungsten carbide as coating material. Tungsten carbide coating is usually prepared by physical vapor deposition, chemical vapor deposition, arc ion plating and other technologies, widely used in tools, molds, aerospace, automotive, machinery and other fields.
In the automotive field, the price of tungsten carbide coating is relatively low, but the service life is also relatively short, generally between tens of hours to hundreds of hours, because automotive engines and other parts need to withstand high temperature, high pressure, high speed and other complex environments in the process of use, which requires higher wear resistance and corrosion resistance of the coating.
In conclusion, the price and service life of tungsten carbide coatings depend on factors such as the specific application and the quality of the coating, and the appropriate coating and preparation process needs to be selected according to the actual needs.
Common ways to maintain tungsten carbide coatings.Protecting and maintaining tungsten carbide coatings is one of the most important measures to extend their service life. The following are some common ways to protect and maintain tungsten carbide coatings:
1. Avoid excessive load on the coating: When using tungsten carbide coated tools, dies and other tools, avoid excessive load to avoid damage such as cracking and flaking of the coating surface.
2. Avoid contacting chemical substances with the coating: tungsten carbide coating has better corrosion resistance, but it is still necessary to avoid contacting chemical substances such as acids and alkalis to avoid affecting the stability and performance of the coating.
3. Avoid coating contact with high temperature: tungsten carbide plate has better resistance to high temperature, but it is still necessary to avoid the influence of too high temperature to avoid affecting the hardness and stability of the coating.
4. Clean the coating surface regularly: Regular cleaning of the coating surface can avoid the accumulation of dust, dirt and other impurities on the coating surface, which can affect the performance of the coating.
5. Keep the coating surface smooth: Keeping the coating surface smooth can avoid the surface from scratching, abrasion and other damage, which affects the performance of the coating.
In conclusion, protecting and maintaining the tungsten carbide coating requires attention to factors such as loading, chemicals, temperature, cleanliness and finish of the coating surface in order to extend the life of the coating. It also requires the selection of suitable coating materials and preparation processes, as well as reasonable usage and maintenance methods to improve the performance and life of the coating.
