Preparation and process optimization of nano-diamond composite plating steel collar

In order to explore the surface of nano composite plating steel collar roughness,microhardness,wear rate and influence on yarn hairiness and end breakage rate, nano-diamond composite coated ring was prepared. The common ring was treated by composite coating method,and nano diamond content,temperature and pH value were selected as 3 main process parameters to carry out3 factors and 3 levels of orthogonal test. The results showed that the optimum preparation process including nano diamond content of 20 g / L,temperature of 85 ℃,and pH value of 5. The surface roughness of the prepared ring is 0. 18 μm,hardness is 635. 8 HV,and the wear volume of 1. 4%.Using such ring for spinning yarns,the yarn hairiness was 2. 18,and the broken number is 3 root /( thousand spindle·h).
