Problems solved by technology

In the process of hot pressing, titanium, aluminum and silicon react violently with each other and release a lot of heat, which causes the blank to react with the mold, which increases the loss of the mold, and it is not easy to demould after sintering
Because the titanium powder in the raw material absorbs a large amount of gas at room temperature, a large amount of gas is released at high temperature and easily forms holes in the blank that are not easy to heal, affecting product quality, resulting in unstable product quality, and the obtained coating material has low density.
Therefore, this process is not suitable for the preparation of high-quality coating materials
