Covalent compounds have strong covalent bond, thus showing high melting point, high hardness, high temperature resistance, corrosion resistance, wear resistance and other excellent performance, is widely applied to the field of refractory materials and wear-resistant materials. But at the same time this kind of material also has the problem of poor toughness and difficulty in sintering. In this article, by adding the nonstoichiometric ratio to the AlN titanium nitride, a new method were studied to improve the sintering property and reduce the sintering temperature through vacancy diffusion and...
