TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.
Abstract: The interpretation of certain phenomena occuring at nominally flat surfaces in stationary or sliding contact is dependent on the assumed distribution of the real area of contact between the surfaces. Since there is little direct evidence on which to base an estimate of this distribution, the approach used is to set up a simple model and compare the deduced theory (e.g., the deduced dependence of the experimental observables on the load) with the experimental evidence. The main conclusions are as follows. (a) The electrical contact resistance depends on the model used to represent the surfaces; the most realistic model is one in which increasing the load increases both the number and size of the contact areas. (b) In general, mechanical wear should also depend on the model. However, in wear experiments showing the simplest behavior, the wear rate is proportional to the load, and these results can be explained by assuming removal of lumps at contact areas formed by plastic deformation; moreover, this particular deduction is independent of the assumed model. This suggests that a basic assumption of previous theories, that increasing the load increases the number of contacts without affecting their average size, is redundant.

TL;DR: In this article, the AlxCoCrCuFeNi alloys with different aluminum contents prepared by arc melting were investigated on their adhesive wear behaviors and the wear mechanism changes from delamination wear to oxidative wear.

TL;DR: In this article, a finite element-based method is presented for simulating both the fretting wear and the evolution of fretting variables with number of wear cycles in a cylinder-on-flat fretting configuration for application to aeroengine transmission components.

TL;DR: In this paper, the authors presented a wear simulation approach with commercial finite element software ANSYS, which is well suited for the solving of contact problems as well as the wear simulation.

TL;DR: In this article, the wear response of different steels and then extended to different hard TiN, TiC coatings under reciprocating sliding conditions is analyzed. And wear energy analysis is transposed, thus allowing the lifetime of hard coatings to be quantified.
