Abstract
A laminated cermet tool material with self generated micro texture on the surface and a preparation method thereof; first, the tungsten carbide titanium matrix powder is added with molybdenum cobalt nickel rare metal as the bonding phase to form the matrix, then 2.5D braided ceramic fiber preforms are placed on the upper and lower surfaces of the cermet matrix powder, and the laminated cermet tool material with self generated micro texture on the surface is obtained by spark plasma sintering, as the ceramic fiber braid is braided, it has a stable structure, realizing the formation of texture coating on the surface of the tool, and the laminated tool with the cermet as the middle layer.
