What are the characteristics of steel-bonded cemented carbides?
Thread Content
Steel-bonded cemented carbide is a type of cemented carbide in which steel serves as the bonding phase and titanium carbide as the hard phase. It has high wear resistance and rigidity (high elastic modulus), as well as high strength, hardness, and a certain degree of toughness. Due to its low density, TiC is lightweight; at the same time, the TiC particles are round, which reduces the friction coefficient and provides good self-lubricating properties. This alloy also possesses good thermal shock resistance, making it suitable for use in environments with rapid temperature changes. Its prominent feature is its good workability and the ability to undergo heat treatment; after heat treatment, there is minimal change in dimensions, with the degree of deformation remaining within the range of allowable dimensional errors. In addition, it also has good weldability and forgeability. The corrosion resistance of steel-bonded cemented carbides varies depending on the type of steel matrix. They have good corrosion resistance in seawater and alkaline solutions; their corrosion resistance in other media and mechanical properties are shown in Tables 15 and 16.
