纳米TiN增强高铬铸铁铸渗层耐磨性的研究
Study on Wear Resistance of High-Cr Cast Iron Cast-Infiltrated Layer Strengthened by Nano TiN
摘要
Abstract
With CO, sodium silicate-bonded sand mold cast-infiltrated technique, the high-Cr white cast iron composite layer strengthened by nano TiN was formed on the surface of the media carbon steel ZG270-500. The influences of the nano TiN on the cast-infiltrated layer microhardness and wear resistance were researched. The results show that under the experimental conditions, when the nano TiN particle was added into the alloy layer, the microhardness of cast-infiltrated layer increases and the wear resistance is the best when the addition of nano TiN is 1.0%. With excessive addition, nano TiN particle tends to be enriched in the interface.关键词
