Do you know what chromium carbide is? What is its function? I believe most of my friends still don't understand these problems. But we don't throw too anxious, today this article mainly for you to tell about some production methods of chromium carbide?. If you are also interested in this topic, then look down with the editor. I hope you can bring some better help when choosing after seeing it.
Although chromium carbide is now used in many industries, most people still feel strange when they see it. Therefore, the first thing we need to know before using chromium carbide can be used for chromium carbide ceramics. Coarse grained chromium carbide is 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. Chromium carbide is widely used in aircraft engines and petrochemical machinery, and can greatly improve mechanical life. Also used for spraying semiconductor films. Its production method is to 13.5 ~ 64% (mass) of carbon black (more than the theoretical combined carbon content of 11.33) and electrolytic chromium crushed into 325 mesh metal chromium powder. Of course, a ball mill may also be used. Use as raw material after dry mixing. 1% to 3% of stearic acid was added as a forming lubricant. The press molding is performed at a pressure of 1T/cm2 or more. Alternatively, the pressurized powder may be placed in a graphite plate or crucible and heated to 1500-1700°C in a stream of hydrogen (hydrogen dew point about -35°C) in a Taman furnace or induction furnace. C, insulation 1h, chromium carbonization reaction to generate chromium carbide, cooling to obtain chromium carbide.
Chromium carbide should be stored in a cool, ventilated, dry warehouse, sealed preservation. In fact, it has many excellent properties, such as strong chemical stability, high room temperature hardness and hot hardness, good acid and alkali corrosion resistance, good wear resistance, high melting point, and good wettability with metals. And in the metal carbide can also have a high oxidation resistance, and the oxidation temperature is also high. When chromium carbide is used as an inhibitor, the grain growth of cemented carbide can be effectively controlled. Especially now in the field of cutting tools, chromium carbide powder usually plays an important role as a surface coating; in Fe-Cr-C alloys, chromium carbide is an important precipitation phase, so that the material has excellent wear resistance. Chromium carbide is a very important wear-resistant phase, and hardness as an important mechanical parameter in the design of wear-resistant materials has not been more accurate results. Due to its high melting point, high elastic modulus, chemical corrosion resistance and wear resistance, it has become one of the most widely used metal carbides.
