“…Composite resins were widely used in dentistry to repair damaged teeth and to restore enamel defects. A number of biomaterials were considered, including ceramics based [387−392], metallic based such as Mg−Co nanocomposites [393], CoCrW-Cu alloys [394] and Ti−Cu alloys [395], and other materials based [328, 396−400]. Coatings and surface treatments were also widely used [401−404], similar to joint tribology.…”

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.

Present study explores the effect of Rice Husk Ash (RHA) reinforcements in mechanically alloyed Al-BN-SiC hybrid composites through experimental characterization. The physical, tribological and corrosion resistance properties of Al-BN-SiC-RHA hybrid composites are studied. In the outset the composite pellets are synthesized using powder metallurgy process. The homogenously amalgamated composite powders are then squeezed together to form multiple green composite pellets each measuring 8 mm in diameter using a hydraulic press at a pressure of 500 MPa. The Al-BN-SiC-RHA hybrid composites are characterized using FE-SEM, EDS, and XRD analysis for facilitating the studies on the microstructural as well as the elemental properties. Microhardness and compressive strength of the Al-5BN-5SiC-5RHA hybrid composites is found to improve by 6 and 13.6% respectively compared to those of Al-5BN-5SiC hybrid composites. The RHA reinforced hybrid composites have also experienced reduction in density and an enhancement in the wear resistance of the composite materials while compared to those for their non-RHA counterparts. The electrochemical corrosion analysis of the Al-5BN-5SiC-5RHA hybrid composites also confirms that the Al-5BN-5SiC-5RHA hybrid composites have better corrosion resistance.

“…They also noted that it was effective on wear resistance. Again Raghav et al [46], in their other studies, synthesized Mg-Co (0-25Co) nanocomposites by powder metallurgy and noted that the microhardness, wear and corrosion resistance of Mg-25Co nanocomposite were better.…”

This paper investigated the wear performances of Y2O3 doped MA6000 (Ni-Cr-Al) alloy produced by mechanical alloying (MA). Produced, all powders were pre-formed by cold pressing and sintered in a vacuum environment. Sintered MA6000-X% Y2O3 superalloys were characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) analysis, density, and hardness measurements. Wear tests of Y2O3 added MA6000 alloys were carried out in a block-on-ring type wear device. In the wear tests, the sliding speed of 1 ms-1 at room temperature (RT) was performed under five different sliding distances (200-1000m) and three different loads (5 N, 10 N, and 15 N). As a result of the studies, it was determined that the MA?ed MA6000 superalloy powders were homogeneous and flake shape. With the increase amount of Y2O3, hardness of these superalloys increased from 267 to 431 Hv, but the density slightly decreased. Different intermetallic/carbur phases such as Ni3Al, MoC are observed in all compositions. Wear tests show that weight loss and wear rate decreased, and friction coefficient (?) increased with the increasing amount of Y2O3 additive. Besides, it was determined that as the applied load increased in the wear test, the weight loss increased, but the wear rate and friction coefficient (?) decreased.
