Abstract: Cladding materials in a substantially powdery state are laminated with a base material in a substantially solid state by compaction under static fluid pressure and thermal treatment for causing sintering of the cladding materials and mutual diffusion at the borders between the cladding material and the base material. The advantages and disadvantages of the component materials compensate each other.
