WC 含量对金刚石钻头胎体性能的影响研究
Effect of WC content on the properties of impregnated diamond bit matrix
摘要
Abstract
Based on the WC-Cu-Co metal bond,the influence of WC content on the metal matrix were researched.Three point bending strength,weight loss and hardness of different WC content were analyzed. x-ray diffractometry (XRD), scanning electron microscope (SEM) and micro-drill experiment were adopted to analyze the matrixes'microstructure and practical drilling effect.Results showed that the matrix's three point bending strength τ0 increased to the maximum,and then reduced with increasing WC content,that weight loss Δm decreased regularly and that hardness HRB tended to increase.XRD showed that Ni1 7 Sn3 was formed as the new phase and SEM showed that 40% WC would be better.Micro-drill experiment showed that 30 wt% and 40 wt% WC in matrix were suitable for medium-hard formation.关键词
