The Mild-Severe Wear Transition in Erosion Wear
Tribology Letters, 2018In 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.

Mild wear maps for boundary lubricated contacts
Wear, 2012In 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.

Simulation of mild wear in spur gears
Wear, 1997Mild 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.

The transition of mild to severe wear of ceramics
Wear, 2004The transition of mild to severe wear of ceramics depends on the operating conditions (normal load, velocity and temperature) and material properties (like grain size, mechanical and thermal material properties). Adachi et al. [Wear 203¿204 (1997) 291] introduced the transition of mild to severe wear of ceramics by defining a mechanical severity ...

Aluminium-silicon alloy, an important material used for the construction of internal combustion engines, exhibit pressure induced distinct regimes of wear and friction; ultra-mild and mild. In this work the alloy is slid lubricated against a spherical steel pin at contact pressures characteristic of the two test regimes, at a very low sliding velocity.

Wear, 1984
Abstract We have measured the weight changes that take place when a martensitic 52100 steel ball slides against a ferritic 52100 steel disc under small loads and at low sliding velocities. The results show that metal is transferred from the ball and appears on the disc as metal oxide.

Transition of Mild Wear to Severe Wear in Oxidative Wear of H21 Steel
Tribology Letters, 2008Under atmospheric conditions at 400 °C, we studied the wear mechanism of H21 steel with different tempering states as a function of normal load. Typical oxidative wear was identified by X-ray diffraction patterns with predominant tribo-oxides of Fe3O4 and Fe2O3.

An examination of a mild wear process
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1957Abstract 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.

The role of carbon in lubricated mild wear
Tribology International, 1986Abstract This paper examines how carbon black (CB) can be used in the study of bore polishing mechanisms. Wear testing was carried out on a modified friction machine with a plane-on-plane combination. The results show a correlation between wear rate and degree of polishing.

A model for the mild ratchetting wear of metals
Wear, 1996Abstract A mechanism of metallic wear is proposed in which laminar wear debris is generated by a process of plastic ratchetting brought about by repeated pummelling of the softer wearing surface by the asperities on a harder mating surface. Wear rate is found to be approximately proportional to (load) 1.5 and an increasing function of a single non ...
