【摘要】 本文分析了金刚石锯片刀头失效的主要原因,并对金刚石锯片的刀头材料、微观组织及其与锯片耐磨性进行研究。通过改进混料工艺,细化了胎体合金晶粒组织,改善了胎体与金刚石的结合状况,提高了胎体合金的耐磨性,使其耐磨率降低了20%。更多还原

【Abstract】 The main causes of segment failure, and the segment material, the microstructure and the wear resistance of diamond saw blade are studied. The microstructure and wear resistance of saw blade material were studied with scan electronic microscope, hardness meter. Suitable blending technique may refine grains, and improve the holding force of matrix to diamond, and enhance wear resistance of matrix to diamond, and decrease wear coefficient about 20%.更多还原
