AbstractA polycrystal model has been developed to study the tribological behavior of an aggregate BCC crystal under extreme contact loading conditions. The polycrystal behavior is defined from the local behavior of a single crystal within the framework of the Hill’s self-consistent scheme by considering the temperature effect. The tribological prob...

The present study is meant to obtain tribological insight into the interface of a rolling rubber wheel on a counter-surface disk based on the work of the previous study Salehi et al. (Tribol Lett 68(1):37, 2020), in which a new test method was developed to rapidly predict tire grip in a laboratory environment. A Laboratory Abrasion Tester (LAT100) ...

AbstractThe influence of the heat transfer field on anomalous film formation under elastohydrodynamic lubrication (EHL) conditions was studied. Liquid lubricant film shapes between a transparent disc and steel ball friction pair were investigated by white light optical interferometry. The fatty alcohol 1-dodecanol was used as the representative lub...

Improving the tactile aesthetics of products that can be described as touch intensive is an increasing priority within many sectors, including the furniture industry. Understanding which physical characteristics contribute to the haptic experience of a surface, and how, is therefore highly topical. It has earlier been shown that both friction and t...

AbstractBi2S3 is a promising solid lubricant for demanding applications, such as oil extraction, heavy mining, and aerospace components. However, its tribological behavior has not been studied in depth. Burnished Bi2S3 soft coatings were evaluated utilizing reciprocating sliding tests under different levels of relative humidity level, normal load, ...

We develop an analytical model of adhesive wear between two unlubricated rough surfaces, forming micro-contacts under normal load. The model is based on an energy balance and a crack initiation criteria. We apply the model to the problem of self-affine rough surfaces under normal load, which we solve using the boundary element method. We discuss ho...

Polyamide 66 is widely used in polymer sliding parts including polymer gear. These parts are used under lubrication of oil and grease. In this study, the friction mechanism of the contact between polyamide 66 and a steel counterpart lubricated with additive-free polyalphaolefin8 oil was discussed by focusing on various parameters including the slid...

AbstractHerein, core–shell structural [email protected] and [email protected] microspheres were prepared using SiO2 as hard core, Cu and MoS2 as shell. As lubricant additives were introduced into base oil (PAO 40), their friction reduction and wear resistance were investigated in detail. Comparing with onefold additive (SiO2, Cu and MoS2), such core–shell structural...
