PURPOSE:To improve the wear resistance of mechanical parts for iron making by forming a hardened and build-up layer wherein carbide particles of W, Nb, V, Ti are dispersed in a matrix. CONSTITUTION:A hardened and build-up layer is formed by dispersing carbide particles of carbide such as W, Nv, V, Ti in a matrix consisting of Fe, Ni, Co as a base in mechanical parts, such as various liners in iron works, which are made of Fe, Ni, Co having the hardened and build-up layer as a base. The unmolten lumped or spherical particles having -8-+30 mesh are used for the carbide particles, and the ratio between the carbide particles and the base part is kept at a ratio of the area of the carbide particles: the area of the base part=4-6:6-4. |
