Impact fretting wear in CO2-based environments
TLDR
In this article, an impact wear model based on the load-sliding distance proportionality of wear and the mechanical response of the impacting bodies was derived and tested against experiment, and the experimental work was carried out on a twin vibrator rig capable of repetitive impact of a moving specimen against a stationary target material.About:

Fretting fatigue and wear damage of structural components in nuclear power stations—Fitness for service and life management perspective
M. Helmi Attia,M. Helmi Attia +1 more
TL;DR: In this paper, a system approach to the fretting wear/fatigue problem allowed the capability of predicting fretting damage through the recognition of the problem nonlinearity, and the effect of self-induced changes.

A generalized fretting wear theory
Helmi Attia,Helmi Attia +1 more
TL;DR: In this article, a generalized fretting wear theory is presented to mathematically describe the wear process under various modes of motion; impact, sliding, and oscillatory, which is based on the findings from the fracture mechanics analysis of the crack initiation and propagation processes.

The wear of metals under unlubricated conditions
J. F. Archard,W. Hirst +1 more
TL;DR: The wear of a wide range of material combinations has been studied in unlubricated conditions as mentioned in this paper, and the wear rate is accurately proportional to the load for only a limited number of combinations but there are many other examples for which the relation between wear rate and load shows only a small deviation from direct proportionality.

Impact wear model for steel specimens
TL;DR: In this paper, a rational model for estimating zero wear conditions in the compound impact (impact accompanied by sliding) wear mode is proposed, and the experimental work well supports the basic tenets of the model; i.e., the existence of a discrete wear factor and the dependence of wear on two crucial parameters: the sliding speed and the stress ratio.

The role of microstructure in the impact wear of two aluminum alloys
TL;DR: In this article, the impact wear resistance of two aluminum alloys was investigated using flat-ended aluminum specimens impacted upon a stainless steel counterface, where the counterface itself was held stationary in some tests (pure normal impact) and moved transverse to the normal impact direction in other tests (compound impact).
