Problems solved by technology

[0003] At present, in the process of compounding oxide ceramics (or nitride ceramics, carbide ceramics) and titanium matrix, due to the poor chemical compatibility and wettability of materials, and the large difference in thermal expansion coefficient of materials, it is easy to cause in oxide ceramics ( Or nitride ceramics, carbide ceramics) materials and titanium composite interface formed between thermodynamic mismatch, resulting in stress concentration, resulting in oxide ceramics (or nitride ceramics, carbide ceramics) material and titanium interface formed cracks or voids, resulting in a serious decline in the hardness, impact resistance, wear resistance, fatigue resistance and other properties of the composite material
