Obtention and Characaterization of the Sn-Ni-Fe-Cu Alloys Applied In Diamond Saw Blade Production

摘要

In the production of metallic saw blades segments impregnated with diamond particles, there are two basic functions of the metal-based matrix. First, to hold tightly the particles and, second, to display wear rate compatible with the diamond loss. The most common matrix materials are composed of either cobalt or iron, nickel, copper, bronze alloys and tungsten alloys. This paper investigated the microstructure and mechanical properties of Ni-Fe-Cu-Sn alloys as the metallic matrix of saw blade segments. It was found that the Ni content significantly influences the microstructure and mechanical properties of the alloy. Information on the diamond bonding efficiency of the Ni-Fe-Cu-Sn alloy as a cutting tool matrix were disclosed.
