In recent years, silicon carbide coating has gradually received more and more attention and application, especially in high temperature, high pressure, wear, corrosion and other harsh working conditions, among which silicone coating can not meet the requirements to a certain extent, silicon carbide coating has become a popular choice of alternatives. Silicon carbide coating, also known as carbon silicide, is a wear-resistant coating composed of carbon and silicon. So, is this coating any good? Let’s talk about our conclusions.
Firstly, one of the advantages of silicon carbide coating is that it has good wear resistance. In such fields as high-speed rail cars, machinery manufacturing, mold manufacturing, aerospace and navigation, the use of silicon carbide coating hardness, wear resistance is greatly improved, so it can improve the service life and durability of the material. For machines and equipment that need to run for a long time, the silicified carbon coating material can even save several costs, because it can reduce the wear and tear of parts, extend the service life of equipment, and greatly reduce maintenance costs.
Secondly, the silicon carbide coating also has certain corrosion resistance and oxidation resistance. In a variety of acid, alkali and other corrosive media and high temperature oxidation environment, silicon carbide coating will not appear obvious corrosion and oxidation, so as to ensure the use of coated objects and quality.
Moreover, the adhesion of silicon carbide coating is strong, can be more firmly bonded to the coated goods, so as to ensure the stability and reliability of the service life. In the industrial production and manufacturing field, as an advanced coating technology, it can also reproduce extremely complex graphics and precision surfaces, so as to meet the needs of high density, high shape precision, high quality requirements of special products.
Of course, there are drawbacks to the silicon carbide coating. First of all, the preparation cost of silicified carbon coating is high, and the use of it requires the corresponding high technology, high equipment and a lot of time consuming processing process, so its cost is relatively high. Secondly, because the silicified carbon coating is formed on the surface of the material in the form of chemical reaction, its thickness and film uniformity are easily affected by many factors such as manufacturing process, sample material and size, so that it can not adapt to some special circumstances.
In summary, silicon carbide coating is one of the high performance and multi-functional coatings. It has the advantages of wear resistance, corrosion resistance, high hardness, oxidation resistance, strong adhesion and other characteristics, but at the same time, there are high production cost, uneven film thickness and other shortcomings. However, compared with the traditional coating, silicon carbide coating has made great progress and its application scope has been gradually expanded. With the continuous development and innovation of technology, it is believed that silicon carbide coating will be applied in more fields and create more benefits and value for people.
