“…The effect of the sharpness of the Berkovich indenter was also investigated. Experimental results show the superiority of nanocrystalline materials, with better convergence for the rounded tip of the indenter [4]. In terms of sports safety research, Hong et al expand safe and healthy life sports activities in Korea by carrying out education, management, and best practices related to life sports safety in Germany and establish an accident prevention system in Korea [5].…”

If there is no protective equipment in martial art single practice, it is very easy to be injured, so protective equipment in martial arts has been paid more and more attention. The protective effect of Wushu Sanda protective gear is related to the safety of every Wushu Sanda practitioner. The purpose of this paper is to study crystalline nanooptical materials and Wushu Sanda protective gear and propose the idea of using more crystalline nanooptical materials in the manufacture and use of Wushu Sanda protective gear. This paper mainly introduces the related content of crystalline nanooptical materials, martial art single-leg kick, and martial art single-leg protective gear and conducts experiments on crystalline nanooptical materials and martial art single-leg protective gear based on crystalline nanooptical materials. The experimental results show that the protective effect of protective equipment based on crystalline nanooptical materials can play a greater role than traditional protective equipment. In the experiments in this paper, the martial art single-leg kicking protective gear based on crystalline nanooptical materials has at least a 10% improvement in protective effect.

“…The experimental results show the advantages of nanocrystalline materials, which can be explained by hall page effect. Good convergence between model and experiment is obtained [4]. Borc J led and discussed the nature of the charge-displacement curve, ejection events and the effect of nanoindentation deformation on the indentation size of the KDP crystal (001) and (100) surfaces under various loads on the head according to Berkovich [5].…”

The indentation unloading curve of ceramic materials describes the contact position and thickness between solid film and substrate. Ceramic films are widely used in modern industry, national defense, military and electronic devices. They have the advantages of low density, high specific strength, high temperature resistance and good oxidation resistance. The film thickness is one of the important parameters reflecting the preparation process. It will not only affect the material itself, but also damage the adjacent surface. Therefore, the mechanical properties should be improved by controlling the pressure applied to the substrate interface. Based on the preparation process, this paper introduces the nano indentation unloading curve test of ceramic thin-layer samples by indentation method, studies the changes of material properties and mechanical properties under different thickness and temperature, and describes the microstructure of ceramic thin-film and analyzes its compactness and microstructure by load displacement curve. After a series of experimental tests, the mathematical description of nano indentation unloading curve of ceramic materials and the method of film thickness measurement are summarized. 1.IntroductionCeramic materials play an important role in modern science and technology and are closely related to people's daily life. Metal film has been widely used in various fields because of its excellent performance, and the indentation problem affects whether the whole industrial application field can realize energy conservation, environmental protection, energy conservation, resource conservation and so on. Ceramic materials have excellent properties such as low density, high hardness, high temperature resistance, easy molding and strong corrosion resistance. It is essential to measure and test the thickness of metal film in practical industrial production.Many scholars have studied the nano indentation unloading curve and film thickness

“…At present, the laser treatment process is well known and is used in many technologies of metal and alloy, as well as in research projects [9,16,[19][20][21][22][23][24]. The ability to form certain mechanical properties of a thin film of an amorphous-nanocrystalline metal alloy without losing the nanostructural state in generally is a fundamental task for many researchers in condensed matter physics, materials science, surface chemistry, and engineering.…”

Amorphous metal alloys have unique properties and are widely used. The unique properties of such materials are accompanied by problems of mechanical strength. The existing methods of their processing are not unambiguous and require a certain approach. In practice, laser technologies allow us to optimize the complex properties of such materials. The selection of optimal processing modes, including the influence of the gas phase, allows you to locally affect the material, increase the microhardness in certain areas. The absence of the influence of the processing medium on the mechanical properties is confirmed. Local impact on the surface sample also leads to an increase in crack resistance. In general, nanosecond laser exposure can be an effective tool for controlling the mechanical characteristics of an amorphous nanocrystalline material.
