The Mild-Severe Wear Transition in Erosion Wear

Tribology Letters, 2018
In this study, three types of abrasives and several types of heat treatments and materials were used to obtain 11 different abrasive/material hardness (Ha/Hm) ratios with the aim of elucidating the effect of the Ha/Hm ratio on the mild-severe wear transition in erosion wear.

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.

The relevance of wear-mechanism maps to mild-oxidational wear

Tribology International, 2002
The presence of oxygen in the environment in which a steel sliding system operates will promote a mild form of wear with wear debris consisting mainly of iron oxides. Of the oxidation-dominated mechanisms, mild-oxidational wear (the prefix describes the extent of oxidation and not the wear rate) has been most extensively investigated.

Automatic classification of severe and mild wear in worn surface images using histograms of oriented gradients as descriptor

Wear, 2019
The main objective of this work was to develop a novel computational strategy that is able to predict wear regime operation in worn surfaces. The image data were taken from worn surfaces images of cast iron specimens subjected to abrasion wear tests ...

Mild wear maps for boundary lubricated contacts

Wear, 2012
In this study a model capable of predicting a mild wear map for boundary lubricated contacts is presented and validated using model experiments. Both the transition from mild to severe wear as mild wear itself is modeled. The criterion for the transition from mild to severe wear is a thermal one.

Mild and Severe Wear of Titanium Alloys

Tribology Letters, 2016
Dry sliding wear tests were performed for TC4 and TC11 alloys on a pin-on-disk wear tester at room temperature and various sliding velocities. TC4 and TC11 alloys shared almost the same wear regularity as a function of sliding velocity and contact pressure.

Simulation of mild wear in spur gears

Wear, 1997
Mild wear in gears is in most cases a smooth process giving initially improved contact conditions followed by a very slow and mild wear process. In some cases the mild wear may cause unfavorable changes of the surface topography, giving non-uniform gear rate, increasing dynamic effects and perhaps more severe forms of tooth failures.

An examination of a mild wear process

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1957
Abstract A detailed study has been made of the wear of hardened high-speed tool steel rubbing on itself at a speed of 66 cm/s under loads of a few kilograms. Radioactive tracers, optical microscopy, reflexion and replica electron microscopy, and other methods of surface examination have been used.
