Tensile test and section analysis on matrix of brazing diamond bit
摘要
Abstract
Mechanical property is a key performance for matrix of drilling bits,which used to be hard to test.Therefore,a new model is designed for sintering specimen.Then the specimen is used to test tensile strength and analyze fracture morphology.Results show that the matrix bonds well with bits and that there is carbonizing reaction between matrix and diamond surface.It is also found that adding diamonds will decrease the tensile strength of the matrix.In this experiment,adding diamond could decrease the tensile strength of matrix up to by 53.8％.关键词
