Abstract
The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.
Highlights
In recent years, research activities in the field of tribology have grown rapidly in terms of both scope and depth
It is found that when a positive potential is applied to the Au surface, a finite height and ordered ice-like water structure is formed at the interface, and a hydrogen bond is formed between the atomic force microscope (AFM) tip and the film, which makes the friction coefficient very large
The research work on lubrious solid coatings is reviewed in the preceding section of 2.4 (Lubrication of surface coatings), while the coatings dedicated to biomedical engineering and high temperature applications are to be discussed in the sections of biotribology and high temperature tribology, respectively
Summary
Research activities in the field of tribology have grown rapidly in terms of both scope and depth. Publications on experimental and theoretical research work have increased enormously in a variety of academic journals, covering phyisics, chemistry, surface science, nanotechnology, materials science and engineering, biomedical engineering, as well as mechanical and manufacturing engineering. To provide a survey on the advances in tribology research, this review paper highlights the development in lubrication, wear, surface engineering, biotribolgy, high temperature tribology, and computational tribology, based on the journal papers published in the period of 2018−2019. It has not been possible to cover all the publications in this review and undoubtedly there have been some omissions. The readers may read the parts they are most interested in as it may be hard to read the entire review from the beginning to the end
