Masking Effect of LPSO Structure Phase on Wear Transition in Mg₉₇Zn₁Y₂ Alloy

Metals, 2021
Room- and elevated-temperature wear tests were conducted using a pin-on-disk testing machine to study wear behavior of Mg97Zn1Y2 alloy and role of long-period-stacking-ordered (LPSO) structure phase in mild–severe wear transition (SWT). Variation of wear

Environmental effects on the wear characteristics of phenolic resin composite (Confirmation of water vapor effects and proposal of tribo-degraded gas effects)

Nihon Kikai Gakkai ronbunshu, 2016
For the purpose of clarifying the water vapor effect on brake pad wear, two experiments were performed. In the first set of experiments, wear tests were conducted using four pads under three relative humidity conditions (0.8%RH, 35%RH and 65%RH).
