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.

Role of wear particles in severe–mild wear transition

Wear, 2005
Abstract Severe–mild wear transition is one of the most interesting phenomena in adhesive wear, because the wear rate decreases drastically after the transition. This paper is aimed at clarifying the mechanism of wear mode transition from severe to mild. A copper pin was rubbed against rotating iron disk in laboratory air.

Dry Sliding Wear Behavior and Mild–Severe Wear Transition of the AA2195-T6 Alloy under Different Loads

Crystals, 2023
The mild–severe wear transition of aluminum alloys is considered evidence that the wear changes from a stable state to an unstable state, which is of great importance in engineering applications.

Role of Wear Particles in Severe-Mild Wear Transition.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1992
The mechanism of severe-mild wear transition and the role of wear particles in that process are studied using a pin-on-disk type wear test rig. Wear particles are continuously removed by air pressure. With the removal of wear particles, severe-mild wear transition does not occur.

Two Types of Wear Mechanisms Governing Transition between Mild and Severe Wear in Ti-6Al-4V Alloy during Dry Sliding at Temperatures of 20–250 °C

Materials, 2022
Dry wear characteristics and wear mechanisms governing mild-severe wear transition of Ti-6Al-4V alloy were studied during sliding against medium carbon chromium steel (50Cr) in an experimental temperature range of 20–250 °C.

Tribological Behavior and the Mild–Severe Wear Transition of Mg97Zn1Y2 Alloy with a LPSO Structure Phase

Materials, 2018
Dry friction and wear tests were performed on as-cast Mg97Zn1Y2 alloy using a pin-on-disc configuration. Coefficients of friction and wear rates were measured as a function of applied load at sliding speeds of 0.2, 0.8 and 3.0 m/s.
