Cermet
Titanium Carbide Tooth Bits, because of its high hardness and wear resistance, is widely used in rock drilling.
There are generally two ways to connect the alloy to the substrate (steel part). One is welding, which uses high manganese steel welding rods to directly weld the steel substrate with the alloy, in this way , there are welding teeth, hobs, etc; The second is press fit connection, which uses drilling on the steel substrate to press the alloy into the hole with interference fit, in this way, there are rotary drill products.
ADVANTAGES
Cermet (steel-bonded cemented carbide) is a composite material produced by powder metallurgy sintering and forging with steel as the binder phase and carbide (mainly titanium carbide and tungsten carbide) as the hard phase.
It has the following characteristics: good process performance，machinability and heat treatability. In the annealed state, ordinary cutting equipment and tools can be used to carry out mechanical processing such as turning, milling, planing, grinding, and drilling. It can also be forged and welded.
Compared with cemented carbide, it has lower cost and wider application range. Good physical and mechanical properties. Steel-bonded cemented carbide has high hardness in the hardened state. Because it contains a large amount of dispersed high-hardness hard phase, its wear resistance can be close to that of high-cobalt cemented carbide.
Compared with high-alloy die steel, it has higher elastic modulus, wear resistance, compressive strength and bending strength.
Compared with cemented carbide, it has better toughness. It has good self-lubrication, low friction coefficient and excellent chemical stability.
