横型半連続鋳造機を用いたクラッド材の作製

抄録

We have developed a semi-continuous caster for a two-layer clad plate for sliding bearing. When the molten metal is poured into a moving mold, it is cooled and molded with a copper roll. Sidedam is a soft material. Therefore, the sidedam is pressed and cooled evenly with a copper roll. To produce a sliding bearing ,a three-layer clad plate consisting of Al-40% Sn-1%Cu alloy plate, an intermediate material and a base material is needed. We used A1050 and ADC12 as intermediate materials for the expeniment. It was impossible to fabricate a clad material having a clear interface between Al-40%Sn-1%Cu alloy and A1050. However, it was possible to fabricate a clad material having a clear interface between of Al-40%Sn-1%Cu alloy and ADC12. It was found that repeated bending test on the fabricated clad material, there was no peeling. In consequence of line analysis, Sn was not observed on the surface of ADC12.
