Experimental Study on Surface Quality of Microbial Removal of Crystalline Copper
The changes of surface roughness and surface morphology of pure copper with different grain sizes are tracked,and the formation mechanism of microbial removal and processing surfaces is studied.The results show that the sur-face quality of pure copper deteriorates with the increase of microbial removal processing time.Grain size have an impact on changes in the surface quality of microbial processing.Different original surface qualities of workpieces have a significant impact on the surface quality of initial stage of microbial removal processing.The scratches formed by the early mechanical processing will gradually become smaller with the microbial removal processing,and when the mechanical surface is re-moved,the main factors affecting the surface quality of microbial processing are the grain boundary and subgrain boundary of the workpiece.
