Abstract
In this paper the results of experimental research on adding of rare earth elements to matrix of diamond tools are discussed. The performance of matrix composites with rare earth elements and free of rare earth elements is measured and the results obtained show that the flexural strength, the hardness and the impact ductility of matrix composites with rare earth elements are improved and the flexural strength increases by 10%～62% over that of the composites free of rare earth elements, and the impact ductility by 5% correspondently. Adding of rare earth elements to matrix materials plays an important role in raising technical and economical indexes of mattix and diamond tools and creates favourable conditions to substitution of Fe for Co in the matrix materials, and it is very prospective.关键词
