Abstract
According to the present invention there is provided a wear resistant material consisting of 3-60% by volume of diamond in a matrix containing at least one hard constituent consisting of carbide, nitride and/or carbonitride of one metal of group IV, V and VI in the Periodic Table and a binder phase based upon Co, Ni and/or Fe at which the diamonds are surrounded by a layer >1 .mu.m of refractory metals, carbides, nitrides, oxides, borides or silicides. In this way, a dissolution of diamonds during the sintering is prevented by a special combination of layer material and sintering compaction process.
