A preparation method of W-plated diamond/aluminum composite relates to a preparation method of a metal-based composite. In order to solve the technical problem that since diamond and aluminum react to produce Al4C3, the obtained composite has poor interfacial adhesion and low heat conductivity. The method includes: first, coating the surface of diamond particles with W; second, preheating; third, infiltrating under pressure: applying a pressure of 10-15 Mpa with an intra-furnace press so that molten aluminum infiltrates the W-coated diamond particles, cooling at a speed of 100 DEG C/h to below 300 DEG C, relieving pressure, turning off a vacuum furnace, and demolding to obtain the W-plated diamond/aluminum composite; diamond is 55-65% in volume fraction, >/=98% in compactness, up to 622 W/(m.K) in heat conductivity, down to 7.08*10-6/K in thermal expansion coefficient and up to 304 Mpa in flexural strength. The invention belongs to the field of preparation of composites.
