Comparation of Friction and Wear Characteristics of Magnesium Alloy AZ91D Formed by Rheo-diecasting and Die Casting Process
The dry sliding friction and wear characteristics of magnesium alloy AZ91D
which were formed by rheo-diecasting and die casting process
were studied at different load、rotate speed and wear time by using an MM-200 abrasion tester. The results show that the wear rate and friction coefficient of magnesium alloy formed by rheo-diecasting process are higher than that of magnesium alloy formed by die casting process in the same expeiment condition. The wear rate and friction coefficient of magnesium alloy enhance with raising the load
and the wear loss mass reduces instead when the load arrives at 250 N. The wear loss of Mg alloy enhances in linearity proportion with the load
but the friction coefficient of Mg alloy do not changed apparently. With increaseing the rotating speed
the weight loss of the alloy can be increased and the friction coefficient can be decreased.
