预烧结温度对热等静压法制备 Co 基金刚石串珠性能的影响
Influence of pre-sintering temperature on the performance of Co-based diamond bead using hot isostatic pressing method
摘要
Abstract
Co-based diamond bead was prepared by hot isostatic pressing(HIP)with appropriate process and parameters.The performance change of matrix after HIP was analyzed and the microstructure of fracture surface was observed by Scanning Electron Microscope(SEM).It could be found that compared to hot pressed sintering,HIP was more contributed to improving the performance of Co-based matrix. The best performance improvement was found in 750 ℃ pre-sintering matrix.The bending strength of matrix was increased by 25.2% and the holding force between matrix and steel substrate was increased by 37.9%.It was obvious that HIP could be used for the preparation of Co-based diamond bead.And it was found that pre-sintering process had a great influence on the matrix's performance after HIP.The best performance of products from HIP could be reached with optimal pre-sintering temperature.关键词
