In this research wear mechanism of ADI under different intensity of loading with different hardness have been investigated. To study of wear behavior, a series of austempered specimens with optimum mechanical properties were used for wear tests. Dry sliding wear tests were carried out in pin-on-ring wear tester machine at speed of 0.5 ms-1 and loaded ...

Wear Mechanism of Nanocrystalline Metals
Journal of Nanoscience and Nanotechnology, 2009Our tribological experiments on nanocrystalline (nc) Ni (grain size down to approximately 10 nm) showed significant reductions in both, the coefficient of friction and wear rate compared to its microcrystalline (mc) counterpart. A consistent relationship was found between grain size, hardness and tribological behavior.

Patients are now keeping their own teeth for much longer than in the past, resulting in many cases of advanced toothwear being referred to specialist clinics. A number of wear processes for the mouth can be identified. Two-body surface-to-surface wear, that may include an element of fatigue, can be identified where patients grind their teeth together,

Wear mechanism of ceramic tools
Wear, 1993Abstract Cutting tests were performed using ceramic cutting tools under continuous cutting conditions. The tests were carried out on AISI 1040 steel, with cutting speeds ranging from 5 to 11 m s −1 . The wear mechanism was investigated for both crater and flank.

A mechanism of hypertrophy and wear of the myocardium
The American Journal of Cardiology, 1965C OMPENSATORY hyperfunction of the heart is an important factor in the development of the general compensation observed clinically in various cardiovascular diseases. It regularly leads to the development of cardiac hypertrophy and later to a gradual weakening of the myocardium.

The mechanism of oxidational wear
Wear, 1995Abstract The mechanism of oxidational wear is carefully studied by microscopic analysis on the wear surfaces and by the measurement of the main factors occurring in the rubbing process of the pin-on-disc configuration. The results show that the occurrence of oxidational wear is governed by the combined effects of normal load and sliding speed.

Extrusion wear and transition of wear mechanisms of steel
Wear, 2008A pin-on-disc configuration was used for studying the wear mechanisms of steel tested in conditions commonly known as oxidational wear regime. The results show that when the nominal contact pressures on the sliding pairs made of medium carbon steel pin/die steel disc and die steel pin/die steel disc at a sliding velocity of 4 m/s were larger than 5.5 ...

Wear-rate transitions and their relationship to wear mechanisms
Acta Metallurgica, 1987Abstract This paper is concerned with ways of classifying wear and presenting the information on a wear map. The unlubricated sliding wear of steel is classified into seven elementary mechanisms of material removal. The two principal modes of wear, namely mild and severe wear, provide an alternative but related classification.

An analysis of the various mechanisms involved in carpet wear has provided the general form of a relationship between carpet thickness and the number of treads on the carpet. The possible applications of this approach in wear testing are discussed.
