Vacuum heat treatment process for steel parts
Definition of vacuum heat treatment of steel parts: The process of heating, insulating and cooling solid steel parts in a vacuum to obtain the desired structure and properties. Objective: To improve the mechanical properties of steel and improve the technological properties of steel. Vacuum annea...
Optimization of vacuum heat treatment of spring
The purpose of vacuum heat treatment is to give full play to the potential of the material, so that it can reach or approach the best mechanical properties, so as to ensure the long-term reliable operation of the spring in the service state. Spring vacuum heat treatment Springs must be subjected ...
Auto Parts Vacuum Heat Treatment
Bearings can be seen in many parts of the car body, which have special missions to bear loads, reduce friction, and guide moving parts. Vacuum heat treatment is a key process in the manufacturing process of automobile bearings, and its processing quality and raw materials are two important factor...
Aluminum Vacuum Heat Treating
The vacuum quenching, aging and vacuum annealing of aluminum alloy vacuum heat treatment mainly depend on the content and proportion of alloying elements. As the temperature increases, the solubility of copper in lead also increases, forming an α solid solution, which has low strength and high pl...
Application of Vacuum Furnace Technology in Automobile Gears
In order to further improve the quality of automobile gears, various vacuum heat treatment processes are used to carry out vacuum heat treatment on gear forging billets, which is beneficial to reduce the probability of irregular deformation of automobile gear forging billets during vacuum carburi...
Vacuum Heat Treatments for Steel
Low-alloy high-speed steel is a new type of steel that appeared in the late 1970s internationally. Due to the use of the latest contemporary alloying principles to determine a reasonable chemical composition, it has good performance and low quenching temperature. Moreover, because of the reductio...
Influence of vacuum heat treatment on tooth surface structure
Advantages of vacuum heat treatment Automobile transmission manufacturers have clear regulations on decarburization of gear teeth. Decarburization may cause problems such as low tooth surface hardness and non-martensitic structure on the tooth surface, which seriously affects the normal use of ge...
Vacuum Carburizing Technology of Automobile Connecting Rod
Vacuum carburizing technology, also known as low-pressure carburizing technology, is in a low-pressure (generally 0-30 mbar) vacuum state, using a pulse method to pass a carburizing medium – high-purity acetylene into a high-temperature furnace for rapid carburizing process. Advantages of v...
Vacuum sintering systems
Vacuum sintering is an important process in the production of powder metallurgy, ceramics, refractory, ultra-high temperature materials, etc. Its function is simply to use heat to densify the powder body. Different applications consider different mechanical properties, thermal conductivity, densi...
Applications of vacuum brazing
YG8 is a tungsten-cobalt material. WC-Co-based cemented carbide has high hardness, wear resistance, good thermal hardness and thermal conductivity, but its impact is low and the market price is expensive. It needs to be connected with steel to exert its excellent comprehensive performance. 0Cr13 ...
