| Abstract: | A rapidly solidified(2024Al)-20Si-5Fe powder alloy has been prepared by two - stage atomization with water-cooling. The microstructure characteristics and wear behaviors have been investigated with electron microanalysis and wear test. The principal test results show that the rapid alloy has finer microstructure and higher wear resistance, as well as good anti-attrition, than that of the cast alloys. The main wearoutfailure ways of the rapid alloy are grain-abrasion and fatigue wear, but grain - abrasion, sticking wear and oxidizing wear occurred in the cast alloy. |
