[Abstract]:With the rapid development of science and technology, many industries have higher and higher requirements for the durability and service life of mechanical parts and equipment. According to the statistics, the energy loss caused by friction accounts for 4050% of the total loss. Therefore, in order to reduce energy loss, new technologies and new methods are widely studied in various industries. In general, the reduction of friction loss of power mechanical parts is mainly studied by the development of lubricating oil, grinding of contact surface and surface plating. Recently, in order to reduce energy loss, improve friction performance and reduce friction loss, many developed countries have extensively studied and applied new surface texturing techniques such as tribology and tribology of micron surface graphics. About a third of the energy used in the world is consumed by friction, and new technologies and methods are widely studied to reduce energy consumption. This paper is a new research method to control friction, improve mechanical properties, prolong service life and reduce energy consumption by optimizing micrometer surface texture. The relationship between the geometric parameters of different surface texture and its tribological response is studied by friction test in order to optimize the friction control of texture. In this study, the processing principle and method of micron surface pattern were established by means of photolithography and electrochemical etching, and the geometric parameters such as shape, size, depth and density of micron surface pattern were deduced by friction test at different pressures. The variation law of friction characteristics under actual working conditions such as speed and lubricating oil. The friction behavior of different micron surface patterns was analyzed by various advanced testing and analysis methods. The results of this paper will provide theoretical and experimental basis for the development of surface texture technology and its application in tribology. In this paper, the micrometer surface figure with different angles is designed and fabricated. Finally, the experimental data are analyzed. Under the condition of paraffin oil lubrication, the contact mode of pin-disk friction pair is adopted under different test conditions. The friction characteristics of micrometer surface figure with different angles are analyzed by using Stribeck curve. Finally, the friction coefficient of micron surface figure with different angles is analyzed by using the friction coefficient map curve under different loads and sliding speeds. The experimental results show that the optimum friction performance is obtained when the angle of the surface figure of the micrometer cross groove is 135 擄.
