采用搅溶加压铸造研制了钢丸增强ＺＡ２７复合材料（ＺＳＣ），复合工艺简便，ＺＳＣ组织致密，钢丸与基体呈冶金结合，切削加工性能良好；在干摩擦和油润条件下，ＺＳＣ的耐磨性随钢丸量的增加而增加，并优于相同试验条件下的ＺＡ２７合金；干摩擦下ＺＳＣ具有自润滑能力和良好的耐磨减摩性能，油润下随滑动速度和载荷的增大其耐磨性较ＺＡ２７更具优势。 The ZSC (steel reinforced ZA27 composite) has been developed by melt-mixing and compression casting. The composite process is simple, the ZSC is dense, the metallurgical bond between the steel and the substrate is good, and the machinability is good. Under the conditions of dry friction and oil lubrication, The wear resistance increases with the increase of the amount of steel balls, and is superior to the ZA27 alloy under the same experimental conditions; under dry friction, ZSC has self-lubricating ability and good abrasion and friction reducing performance. With the increase of sliding speed and load Its greater wear resistance than ZA27 more advantages.
