Hard alloy is a refractory metal with high hardness

Date of release:2018-05-27 Author: Click:

Powder metallurgy products sintered in a vacuum furnace or hydrogen recovery furnace.Because of the hardness and melting point especially high alloy rotary file;Collectively known as cemented carbide.Carbide is a kind of hard refractory metal carbide (WC, TiC) micron powder as the main component, the following carbide as the focus to clarify the hard gold-bearing layout, characteristics and use, cobalt (Co) or nickel (Ni), molybdenum (Mo) as the binder.Rotary file

Because carbon atom radius small, Ⅳ, Ⅴ B, B Ⅵ B group metal carbide, nitride, boride, Ⅳ A, A and Ⅵ Ⅴ consisting of A metal and carbon type metal carbides.It forms a solid solution in the open space, which can be filled in the open space of metal quality and retain the original lattice mode of metal until it reaches the fullness stop and changes between 5 and TiC.Such solid solution can continue to dissolve its constituent elements when the dissolved carbon content exceeds a certain limit (for example, Ti: C=1:1 in titanium carbide).The mesenchyme solid solution is called a mesenchyme compound, and its composition can vary within a certain range (for example, the composition of titanium carbide is at TiC0.

Meanwhile, hafnium carbide and tantalum carbide are 4160K and 4150K respectively. The hardness of most carbides is very high. The microhardness of 1800kg·mm2 is equivalent to mohs -- diamond -- hardness 9).Titanium carbide has the best thermal stability of all carbides, but metallic carbides can be said to be a major disadvantage of carbides.The composition of the interstitial solid solution, is known at that time of the highest melting point of the material, can conduct electricity, heat conduction, high melting point, hardness, another some of the metal alloy bonding rotary file.Many carbides are not easy to differentiate under high temperature and can resist oxidation better than their constituent metals.

Under appropriate conditions, it is a kind of very important metal carbides, especially Ⅳ, Ⅴ B, B Ⅵ B group the melting point of metal carbides are above 3273 k.In the oxidation atmosphere, all carbides are simply oxidized at high temperature. The chemical formula does not conform to the valence rules.Nitrogen atoms, boron atoms can also enter the open space of the metal lattice.Thus, they have similar properties to mesenchymal carbides, and their microhardness is greater than 1800kg·mm2.Together brittleness is also big, the matrix of hard alloy is composed of two: one is some hardened phase, make the original metal lattice into another way of metal lattice.
