| Abstract |
A carbon steel/Cr-cast iron bimetal produced by an alloy cored wire welding method showed a zigzag type fracture in the interface in tension tests. Results obtained from the interface were; σ_(UTS) = 29.75 (㎏/㎟) σ_(ys) =20.08 (㎏/㎟) E = 8.5 × 10＾7(psi). The evaluated value of J_(IC) was 0.7 ㎏.f/㎜. Brittle fracture were observed only in the cant structure. Wear resistance of hardfaced metal was superior to that of base metal. The wear mechanism was mostly abrasive wear. but oxidation wear and adhesive wear were also activated partly. |
