Effect of cryogenic treatment on eta phase
The eta phase is a tungsten-cobalt-carbon ternary compound formed by the participation of some Co atoms during the cooling process after sintering of cemented carbide. The dissolved W in Co cannot form WC. This provides the opportunity for cryogenic treatment to further promote the formation of t...Read more -
Effect of cryogenic treatment on wear resistance of cemented carbide Cemented carbide is an ideal material for wear-resistant parts.
Cemented carbide is an ideal material for wear-resistant parts. However, traditional cemented carbide products can no longer meet the increasingly stringent usage requirements. In recent years, the use of cryogenic treatment technology to make up for the shortcomings in wear resistance of traditi...Read more -
Effect of cryogenic treatment on mechanical properties of cemented carbide
The mechanical properties of cemented carbide are mainly reflected in hardness, flexural strength, compressive strength, impact toughness, fatigue strength, etc. Whether cryogenic treatment can improve the mechanical properties of cemented carbide is the most intuitive expression of the ef...Read more -
Development of cryogenic treatment of cemented carbide in China
Since the advent of cemented carbide in 1923, people have continuously optimized its properties mainly by improving its sintering process, preparing ultra-fine WC-Co composite powder, and surface strengthening. However, due to the problems of complex equipment, high preparation costs, and high te...Read more -
Carbide quenching and tempering process
Quenching process The purpose of quenching is to transform the matrix into martensite and obtain higher mechanical properties. Due to poor thermal conductivity, preheating is required. The hard phase carbides in steel-bonded cemented carbide prevent the growth of austenite grains. After the alloy...Read more -
