Experimental Analysis of Self-healing Performance of Friction Interface of Copper Based Powder Metallurgy Materials
In order to explore the self-healing performance and influencing factors of the friction interface of copper based powder metallurgy materials,a comprehensive and systematic investigation was conducted.The materials and equipment used in the experiment were introduced,and the experimental process and evaluation indicators were discussed.It was pointed out that the experimental process should scientifically design accessories such as grinding columns and dual steel plates,and scientifically select evaluation indicators such as plow groove width and friction coefficient.On this basis,the results are summarized and presented,starting from the three influencing factors of temperature,speed,and pressure,to analyze the self-healing performance of the friction interface of copper based powder metallurgy materials.The results show that within a certain range of values,the increase of temperature,speed,and pressure can promote material self-healing,and the influence of pressure is particularly significant.Temperature,rotational speed,and pressure have a certain impact on the self-healing ability of the friction interface of copper based powder metallurgy materials.In practical use,the wear resistance of the material can be improved and the service life of the material can be extended by adjusting the parameters.
