发明名称 Wear-resistant overlay forming method and wear-resistant composite members
摘要 PCT No. PCT/JP95/01522 Sec. 371 Date Apr. 2, 1996 Sec. 102(e) Date Apr. 2, 1996 PCT Filed Jul. 31, 1995 PCT Pub. No. WO96/04097 PCT Pub. Date Feb. 15, 1996A wear-resistant overlay forming method wherein hard particles are supplied to a molten weld pool that is formed on a base material by an arc generated from an arc electrode to form a wear-resistant overlay containing hard particles on the base material, and wherein the hard particles are supplied to part of molten metal of the molten weld pool, the part being raised by the arc or flowing down owing to gravity. A wear-resistant composite member for cutting and removing rock and sand is designed such that the hard-facing deposit layers containing the hard particles are formed on the base material in a stripe pattern so as to run in the direction of friction produced by rock and sand or such that the hard-facing deposit layers containing the hard particles and soft-facing deposit layers made from soft material are formed on the base material in a stripe pattern so as to run in the direction transverse to the direction of friction produced by rock and sand, being alternately aligned in the direction of friction.
