Chromium carbide wear-resistant steel is a wear-resistant, wear-resistant and heat-resistant carbide tool plate. Its function is higher than that of other carbon steel wear-resistant lining plates. It is widely used in decorative building materials, concrete and thermal power generation energy industry. Its wear resistance is only second to high chromium white cast iron and better than medium carbon steel and vertical high alloy steel, ranking first in carbon steel raw materials. Because the chromium composition is also high, it can block or alleviate the precipitation and growth of carbides during quenching, so that the carbide can maintain a relatively large particle size distribution, and also help to improve the hardness and toughness, that is, the tempering stability can be good, and has a certain level of high temperature oxidation resistance, so that the scope of application is relatively wide.
The carbonation circuit (CnC) has a relatively low 1710 of culture sites. The relative density is 6.68g.m). Thermal expansion index 10.3x10 ~ K(20-100) Thermal conductivity 19.1W.m- .K-1. The key feature is that the strength and hot hardness of the carbide complex are very high at room temperature, and CoNi and other metals have good lubricity, and the oxidation resistance in the metal-shaped nitrogen compound is large. The air needs to be oxidized in the 1001400 before it is more serious. Good corrosion resistance. It is a raw material with good comprehensive ability to resist high temperature oxidation friction and wear and resistance to natural gas corrosion. Widely used in heat-resistant coating, but immediately painted chromium carbide coating, adhesion is weak. Therefore, the key is an important raw material component for the preparation of NiCr-CrC2 composite powder.
Chromium carbide coating shall be sprayed with chromium carbide electrostatic powder. Chromium carbide can meet the heat damage regulations and developed a metal ceramic powder, its melting point is about 1400 degrees. The coating to be sprayed with electrostatic powder is mainly used in the work in the ambient temperature of 540~815 ℃, and the specified surface has the characteristics of anti-sanding particles, high toughness, fretting wear resistance and abrasion resistance. It is a kind of wear resistance and oxidation resistance composite material coating.
Chromium carbide ceramic coatings are mainly used in automobile engine motor rotors, turbine engine leaves, turbine engine end face seals, plasma spraying nickel-chromium alloy turbine engine noise-canceling partition automatic exhaust valve protruding surface, thermoforming mold rollers and super-breeding fast flames to eat and coat pipes containing high temperature damage in the combustion chamber of coal-fired steam boilers.
the characteristics of chromium carbide:
Gray, orthorhombic crystal system. It has metallic texture, 6.68 density, melting point 1890 ℃, melting point 3800 ℃, microhardness 2700kg/mmz, linear expansion coefficient 11.7 × 10-6/℃. Acid resistance, alkali resistance, insoluble in water. Continuous high temperature oxidation, 1100 ℃ in the air under the condition of 4h without air oxidation.
