[0002] Titanium diboride (TiB 2 ) is the most stable compound of boron and titanium. It is a ceramic material with high melting point, high hardness and high elastic modulus. It also has good electrical conductivity, thermal conductivity, wear resistance and acid and alkali chemical corrosion resistance. Like most ceramic materials, it is brittle, which limits its application range as a structural material
Theoretically speaking, soft-hard laminated materials such as titanium diboride / metal have excellent strength and toughness, but there are very few technical reports on the successful preparation of titanium boride / metal laminated materials. The reason is that most metal materials will chemically react with titanium boride at high temperature and form a corresponding brittle ceramic phase, thus losing the characteristics of this soft-hard combination structure and failing to achieve the purpose of toughening; a small amount can react with boron at high temperature Metals with titanium boride that maintain chemical stability are difficult to achieve a good bond between the titanium boride ceramic layer and the metal layer due to poor interface wetting properties, which greatly reduces the strength of the laminated material and fails to achieve the purpose of toughening
