Automobile gear carburizing process
The transmission gear of automobile rear axle is an important part of automobile transmission mechanism, and carburizing is an extremely important production process of automobile gear. In addition to pressure resistance, wear resistance, impact resistance, plastic deformation resistance, surface...
Advantages of Low Pressure Pulse Vacuum Heat Treatment
Heat treatment is one of the four basic industries (casting, forging, heat treatment, welding) of mechanical manufacturing, and is a very important key process in the manufacturing process of mechanical products. Mechanical engineering is inseparable from die engineering, which is closely related...
Improvement of Machinability of Parts by Vacuum Heat Treatment
In the production process of many enterprises, it is often found that there is a problem of deformation in the cutting process of parts. In order to reduce the quenching deformation of these parts, the salt bath furnace heating isothermal quenching process is generally used for heat treatment. Th...
Advantages of vacuum sintering of tungsten cobalt carbide
A typical representative of commonly used cemented carbide, tungsten-cobalt cemented carbide (YG-type cemented carbide) refers to an alloy composed of tungsten carbide as a hard phase and metal cobalt as a binder phase. In terms of use, tungsten-cobalt carbide can not only be used to make cuttin...
Research on Properties of H13 After Vacuum Nitriding
1 Vacuum nitriding test H13 hot work die steel is the most widely used in many hot work die steels, and its alloying elements are mainly V, Cr, and Mo. Before the experiment, the H13 steel sample was cut out for vacuum oil quenching at 1075 °C, and then subjected to vacuum tempering at 550 °C for...
Vacuum heat treatment of main and driven gears of automobile main reducer
The driven large gear and the driving pinion used in the automobile reducer are generally made of 20CrMnTi material, and the quality requirements are very strict. In actual production, we have formulated and implemented the following vacuum heat treatment process. The driven large gear adopts thr...
MIM Technology to make tiny parts
The latest smart phones, small high-performance UAV engines, micro robot gearboxes or other mechanical structures all demonstrate the demand for system miniaturization in the world today. Traditional processing technology takes a long time, has large defects and low yield. However, if the MIM pro...
