Problems solved by technology

[0002] However, traditional wear-resistant metals cannot adapt well to this harsh grinding environment. Especially in high-temperature environments, they are prone to high friction loss, multiple deformations, and multiple breakages, which have a great impact on their service life. In order to adapt to this harsh working condition and achieve a better grinding effect, it is necessary to find a high temperature resistant, strong impact resistant, strong corrosion resistant, etc., and the existing wear-resistant metal sheets generally have poor oxidation resistance.
