喷射成形ZA35合金的摩擦磨损行为

rapidly solidified ZA35-3.5%Mn alloy has been prepared by spray forming technology. The wear behaviors have been investigated with electron microanalysis by friction and wear test. The principal test results show that with the temperature increase, the friction coefficient of spray forming alloy increases slightly. Spray forming alloy exhibits excellent wear resistance, as well as good anti-attrition than those of the cast alloys with the similar composition. The main wear-out-failure ways of the spray forming alloy are grain-abrasion and fatigue wear, but for the cast alloy the main ways are grain-abrasion, sticking wear and oxidizing wear
