LAYER STRUCTURE SINTERED SUPER ABRASIVE PARTICLE COMPOSITE MATERIAL AND MANUFACTURING METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a sintered material having increased high temperature stability in a layer type composite material in which a super abrasive particle sintered body and a heterogenous material and increased utility capable of soldering on both faces, and an effective manufacturing method of the sintered material.SOLUTION: There is provided a sintered super abrasive particle composite material having a layer structure by conjugating a layer of a hard metal material on one surface of a sintered super abrasive particle material layer and a metallic layer consisting of a first metallic material on another surface, (1) the sintered super abrasive particle material layer and the hard alloy material layer are integrated by a same time sintering treatment in a pressure and temperature condition in which super abrasive particles are in thermodynamically stable pressure and temperature range, and (2) a first transition layer formed by the treatment between the metallic layer and the super abrasive particle material layer exists and particle size of a compound crystal with a super abrasive particle constitutional element of a first metal and/or first metal concentration in the first transition layer exhibit gradient variation between both layers.SELECTED DRAWING: Figure 1
【課題】超砥粒焼結体を異種材と接合した積層型の複合材において高温安定性を増すと共に、両面においてロウ付け可能な利用性の増した焼結材、及びかかる焼結材の効果的な製法を提供する。【解決手段】焼結超砥粒材層の一方の面に超硬合金材の層、他方の面に第一金属材からなる金属質層が接合された積層構造を持つ焼結超砥粒複合材であって、(1)上記焼結超砥粒材層と超硬合金材層及び金属質層とは超砥粒が熱力学的に安定な圧力温度領域内の圧力温度条件内での同時焼結処理によって一体化され、かつ(2)該金属質層と超砥粒材層との間に該処理によって形成された第一遷移層を有し、該第一遷移層において、第一金属の超砥粒構成元素との化合物結晶の粒度及び／又は第一金属濃度が上記両層間で傾斜的な変動を呈する積層複合材とする。【選択図】図１
