Correlation between test temperature, applied load and wear transition of Mg97Zn1Y2 alloy
Journal of Magnesium and Alloys, 2021 Dry sliding wear tests were performed on Mg97Zn1Y2 alloy at various temperatures of 20, 50, 100, 150 and 200 °C using a pin-on-disc wear testing machine in order to reveal mild-severe (M-S) wear transition mechanism during elevated-temperature wear ...

Research on the Timing of Replacing Worn Milling Cutters by Using Wear Transition Percentage Constructed Based on Spindle Current Clutter Signals [PDF]
SensorsThe use of worn cutters not only reduces the machining accuracy but also increases the surface roughness. Therefore, it is important for enterprises to establish replacement rules for worn cutters.

Wear transitions in a wear coefficient model [PDF]
Wear, 2009 The frictional-work wear model has been used popularly for the prediction of wear phenomena such as rail corrugation. The accuracy of such models depends on the value chosen for the empirical wear coefficient in this wear model. Experimental results have widely shown that this wear coefficient is strongly dependent upon the type of wear process ...

Acoustic Emission Signals and Wear Phenomena on Severe-Mild Wear Transition
Tribology Online, 2008 The relationship between acoustic emission (AE) signals and wear phenomena in severe-mild wear transition is discussed on the basis of the results of observations of wear particles and worn surfaces of steel.

Mapping rail wear regimes and transitions [PDF]
Wear, 2004 This paper outlines work carried out to produce maps of rail material wear coefficients taken\ud from laboratory tests run on twin disc and pin-on-disc machines as well as those derived from\ud measurements taken in the field. Wear regimes and transitions are identified using the maps\ud and defined in terms of slip and contact pressure.

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
