Abstract

PURPOSE:To provide excellent grindability in case of application to the accurate grinding of fine ceramics, by allowing a Co-Ni-Sn metal-base diamond sintered compact to be held by a base phase consisting of Ni, Sn, and Co. CONSTITUTION:The diamond sintered compact is produced by mixing, for the purpose of holding, a diamond powder of 30-300mu average grain size with 1-10mu Co and Ni powders and 10-100mu Sn powder by 10-30wt% and then by sintering the resulting powder mixture. This diamond sintered compact has a structure in which diamond powder is held by the base phase having a nonuniform structure consisting of 5-30wt% of Ni and Sn and the balance Co.
