Description

Technical Field

[0001] The invention relates to the field of friction and wear mark detection equipment, and in particular to an ultra-high temperature environment friction and wear in-situ radiation detection system. Background Art

[0002] With the rapid development of science and technology and the continuous expansion of industrial applications, the requirements for material performance in extreme environments are becoming increasingly stringent, especially under high temperature conditions. Traditional lubricants often fail and cannot meet the requirements. High-temperature solid lubricating materials have shown important application value in many fields with their excellent high temperature resistance, low friction coefficient, high load-bearing capacity and good chemical stability. High-temperature solid lubricating materials are widely used in key hot end components of core devices such as aircraft engine bearings and their transmission systems, missile all-gas servo mechanisms, and rocket engine thrust chambers. However, my country's research on high-temperature wear-resistant self-lubricating materials started late, and there is a lack of systematic research and basic application data on such materials. The reason is that in addition to the core technology and process of materials, the lack of friction and wear testing equipment with the ability to simulate near-service conditions is the key to limiting the improvement and application of material performance. When materials are subjected to friction and wear in ultra-high temperature environments, their microstructure changes, phase changes, defect generation and evolution laws cannot be monitored in real time. There is a lack of research data on the generation and failure of their lubrication mechanism, which cannot guide the optimization and design of materials in depth.

[0003] For the detection of friction wear marks, patent CN 110095370 A discloses an online dynamic visual wear mark analysis experimental device and method, and patent CN 209400822 U discloses a friction test device. The two patents are mainly based on the normal temperature friction test equipment with an optical microscope to observe the width and microscopic morphology of the wear marks. It is impossible to achieve real-time monitoring of the crystal structure changes and material phase changes of the material during friction and wear. Especially when the friction test is carried out in an ultra-high temperature environment, the wear debris transfer and reaction will occur between the materials in relative contact and friction. The new phase generated will change due to the change in the organizational composition, resulting in the change of the lubrication performance of the material, which has a key impact on the design and development of new materials. Therefore, the generation of new phase crystals is closely related to the environment such as temperature, and the analysis of this microstructure is not achievable in the above patents. In addition, the above patents can only realize the adjustment of the upper and lower focal lengths of the optical lens, and cannot observe the wear mark morphology from multiple angles. Therefore, it is very urgent to develop a device that can perform in-situ radiation detection of wear marks during ultra-high temperature friction. Summary of the invention
