TL;DR: In this paper, the effect of surface wettability of different materials on friction and wear behavior with sliding friction of 100% has been studied with a pin-ondisc tribometer with homogeneous and heterogeneous couplings in dry conditions and with oil and water lubrication.

TL;DR: This work presents an alternative bearing surface in the field of total hip replacements that is composed of a polymer composite polyether-ether-ketone (Peek) as the matrix and a carbon fibre as reinforcement.

TL;DR: In this article, the influence of some factors which characterize material surface state, such as hardness, roughness and surface degreasing, on material wear behavior has been analyzed, and an attempt to set the optimal conditions for standardized tests, has been made.

TL;DR: In this paper, the formation of thin protective films consisting of reaction products between the alloys and the ambient atmosphere is attributed to the rapid formation of a uniform, highly protective passive film.

TL;DR: In this article, the failure cause of two types of piano strings made of spring steel wires with different thickness were systematically analyzed and the numerous problems which make it difficult to quantify the string life are systematically analyzed.
