Comparison on the rolling-sliding dry friction property of AZ91 and AZ91-Y alloy
Cailiao gongcheng, 2020 The rolling-sliding dry friction properties of AZ91 and AZ91-Y (1.0% Y) (mass fraction)were studied with 45 steel as friction pair. The experiment was carried out under different normal loads (100,200,300 N), respectively.
