20CrMnTi steel is a good performance of carburized steel, which has high hardenability, good wear resistance, small grain size, good carburizing quenching performance, low temperature impact toughness, strong normalizing after cutting performance, low price and other advantages, is widely used in...

Vacuum heat treatment technology of heavy duty gear

Gear is widely used in manufacturing industry. It should have excellent wear resistance, contact fatigue and bending fatigue strength. There are many kinds of gear. For large gear, it can be divided into soft gear, hard gear and hard gear. In the 1950s, the large gear with low speed and heavy loa...

Vacuum heat treatment of aviation impeller

In the aviation industry, a large number of high-strength, high-precision metal parts are required. The processing of these metal parts is inseparable from the heat treatment process. Among all heat treatment processes, vacuum heat treatment is widely used because of its excellent properties. Dir...

Vacuum Sintering of Quartz Ceramics

Quartz ceramics, also known as fused quartz ceramics, quartz glass ceramics, sintered quartz glass products, sintered fused silica products, are products prepared by using fused quartz or quartz glass as raw materials through a series of ceramic processes such as crushing, forming, and firing. I...

17Cr2Ni2Mo Steel Gear Vacuum Carburizing

When the gear is working, it must not only bear a large impact load, but also bear alternating bending stress and contact stress. Therefore, the gear should have high strength, impact toughness and good fatigue resistance. When the gear pair meshes, the pressure and friction coefficient at the co...

Classification and selection of vacuum carburizing process

1.Direct quenching and low temperature tempering Structure and performance characteristics: Can not refine the grain of steel. The quenching deformation of the workpiece is large, the residual austenite on the surface of the alloy steel carburized part is more, and the surface hardness is lower. ...

Vacuum pressureless sintering of boron carbide ceramics with additives

Boron carbide ceramic materials have many excellent properties, such as: high melting point (2450°C), ultra-high hardness (HV>30GPa), low density (2.51g/cm³), high modulus, good wear resistance, oxidation resistance, Strong acid and alkali resistance, good neutron absorption capacity, and high...

Aircraft engine rectifier vacuum brazing

The material of the 5~8 stage rectifier of the aero-engine is Ti-6AI-4V titanium alloy. It is required to braze 60~80 blades to the inner and outer rings at the same time. The smaller the amount of deformation required as a whole, the better. When assembling before vacuum brazing, the blades are...
