Problems solved by technology

[0002] With the rapid development of science and technology, people have higher and higher requirements on materials (especially the materials used in key components). Researchers not only focus on the improvement of basic properties such as material strength and hardness, but also on the fatigue life of materials. Higher requirements are put forward. Therefore, how to effectively improve the fatigue life of materials has become one of the most important topics for scientific researchers. The liquid-solid mixed jet method is one of the important methods for surface strengthening, which is of great significance to improve the fatigue life of materials. , the current research on liquid-solid mixed jets is not deep enough, mostly staying at the theoretical analysis level, and there are few researches on experiments and further engineering applications
