Chromium carbide industry prospects for the development of this industry is very good, because in the use of the benefits for the enterprise more, so favored by customers, in order to make you more familiar with it, then we will tell about the advantages of chromium carbide.
Nowadays, there are still many people who do not know some basic information about chromium carbide. Therefore, as a manufacturer, it is necessary for us to explain briefly. In fact, chromium carbide has many excellent properties such as strong chemical stability, high room temperature hardness and hot hardness, acid and alkali corrosion resistance, good wear resistance, high melting point, and good lubricity with moisture and other metals. In the metal type carbide, the oxidation resistance is high, and the oxidation temperature is also high. When chromium carbide is used as an inhibitor, it can effectively control the growth of cemented carbide grains. When the product is used, during the processing, the carbon in the matrix continuously diffuses to the surface of the carbide hard deposit, and combines with the adsorbed active chromium atoms to gradually thicken the deposit, thereby forming a certain amount of carbon on the surface of the sample. Thick chromium carbide coating. The processing method has the advantages of convenient operation, low cost, uniform coating and low environmental pollution. Chromium carbide is now used as a meltblown material to form a meltblown coating on the surface of metals and ceramics, giving the latter wear resistance, heat resistance, corrosion resistance and other properties. Widely used in aircraft engines and petrochemical machinery, greatly improving mechanical properties. Also used for sputtering semiconductor thin films.
Chromium carbide is a gray powder with an orthorhombic system. It has metallic luster, 6.68 relative density, melting point 1890 ℃, boiling point 3800 ℃, microhardness 2700kg/mmz, thermal expansion coefficient 11.7 × 10-6/℃. Acid and alkali resistant, insoluble in water. Good high temperature oxidation resistance, no oxidation in the air at 1100 ℃ for 4 hours. Now chromium carbide is not only an additive with good wear resistance, but also a high-quality metal ceramic raw material. It can also be used as a spray powder. For example, the spray powder has good high temperature corrosion resistance and oxidation resistance, and abrasion resistance. Of course, due to the excellent performance of chromium carbide, it has been widely used in metallurgical industry, electronic industry, high temperature resistant coating, aerospace and other fields. In addition, we should also know that the chromium carbide coating process of the slag method is to place the carbon-containing sample to be coated in the slag of a certain temperature and composition, and the composition of the slag reacts to generate carbide-forming element active chromium atoms. The active atoms reach the surface of the sample through diffusion, and combine with the carbon atoms on the surface of the sample substrate to be coated by adsorption and chemical reaction to form chromium carbide deposited on the surface of the substrate.
After the introduction of the above content, we also have a further understanding of the advantages of chromium carbide. When I see him again in the future, I will not feel strange, and there will be no frequent problems in the process of using it. Well, that's all for today's content. I believe it will bring more wonderful knowledge points.
