Carburizing treatment
It is the process of incorporating carbon atoms into the surface layer of steel. Generally it is low carbon steel or low carbon alloy steel (carbon content is less than.). For materials such as steel, after carburization, its hardness can reach the highest level, and the carburization depth can reach about -10 degrees.
The chemical composition of the steel surface can be close to that of high carbon steel. After carburizing, the workpiece must be quenched to obtain high surface hardness, high wear resistance and fatigue strength, and to maintain the strength and toughness of the quenched low carbon steel in the core, so that the workpiece can withstand impact loads. The carburizing process is widely used in mechanical parts such as aircraft, automobiles and tractors, such as gears, shafts, camshafts, etc.
In order to meet the requirements of parts with hard surface, wear-resistant core and good plastic toughness, this problem must be analyzed and studied from the aspects of material use and heat treatment process. If high-carbon steel is selected for quenching and low-temperature tempering, although it has It has high hardness and good wear resistance, but its plastic toughness is low and cannot meet the requirements. After quenching, high carbon steel materials have high hardness and good wear resistance, but their plastic toughness is low and cannot meet the requirements. Although the low carbon steel material has good plastic toughness after quenching, it cannot obtain a surface layer with high hardness and wear resistance, which also cannot meet the requirements. If you choose low carbon steel for carburizing and quenching, you can get satisfactory results. This is the purpose of carburizing.
Carburizing is widely used, such as: mechanical parts, such as cams, eccentrics, gears, piston pins and other parts, the surface is subjected to strong friction when working and bears impact load. Therefore, the surface is required to be hard, wear-resistant, The heart should have good plasticity and toughness.
