The recent progress of tribological biomaterials

Abstract

Tribological phenomena abundantly exist in living beings, especially in human beings, such as teeth, eyes, bones, skins, heart valves and so on, and it is of meanings to reveal the mechanism of tribology in human body and fabricate artificial biomaterials to replace the damaged tissues to release the pain of patients. Alloys, ceramics and polymers are three uppermost materials used in engineering and some of them play a crucial role in biomedicine. In the paper, we provide an overview of the tribological behaviors of artificial biomaterials including alloys, ceramics and polymers. We aim to provide fundamental mechanistic and applications of tribological biomaterials, while emphasizing the advantages and disadvantages of various kinds of tribological biomaterials. Finally, some challenges and the potential promising breakthroughs are also succinctly highlighted in this field.

Development and characterization of chitosan-grafted polycaprolactone / Poly (3-hydroxybutyrate-CO-3-hydroxyhexanoate) fiber blends for tissue engineering applications

“…A similar trend is found for the wear rate: there is about 2-fold reduction in the specific wear rate of the 70/30 mixture compared to neat PBHHHx. The observed decrement likely has also a strong correlation with the morphology of the samples: PHBHHx and the 30/70 blend have a grainy appearance, with many small pores, whilst CSg-PCL and the 70/30 blend exhibit fewer and larger pores, and reduction in porosity is advantageous for improving tribological properties [16] since the debris accumulates into the pore spaces within the fiber mat, consequently roughening the surface and increasing the coefficient of friction, and in turn, leading to abrasive wear.…”

A Perspective on Biotribology in Arthroplasty: From In Vitro toward the Accurate In Silico Wear Prediction

“…Clinical research in the joint prosthetic field, with the aim of evaluating the performance of new biomaterials from a tribological point of view, is essential to prevent the onset of unexpected failures [67]. Continuous improvements are needed on the wear tests, which must take into account the tests performed in vitro (using joint simulators) in order to accurately replicate the behavior in vivo.…”

An Essential Studies on Tribology’s: A Short Review

“…The tribological cooperation of the uncovered face of a strong surface with interfacing materials and conditions can lead to material loss from the surface. At the atomic level, the crystal lattices of the two strong contact materials are in a balanced state [18,19]. At the point when a shear pressure is connected to one segment, the two cross-sections disfigure flexibly.…”
