“…The density and porosity of the sintered samples were determined by Archimedes method according to the standard of ASTM‐C373‐88 46 . The theoretical density of the composite sample was calculated according to the law of mixtures and according to the density of SiC (ρSiC) which was equal to 3.21 g/cm 3 , 15‐18 the density of B 4 C ( ρ B 4 C) which was equal to 2.52 g/cm 3 47 and the density of Resin Phenolic ( ρ R) which was equal to 1.32 g/cm 3 48 . The calculation was based on Equations () and ().

In this research, carbon sources (Resin Phenolic, Carbon Black and Graphite) and Boron Carbide (B 4 C) were used to improve the mechanical properties of Silicon Carbide (SiC) composite. For this purpose, carbon sources of 0.5, 0.75, 1, 1.5, 2, 2.5, 3, and 5 wt% as well as 0.5 wt% B 4 C were added to SiC powder, respectively.The sample containing SiC-2.5 wt% Resin Phenolic-0.5 wt% B 4 C had the best properties with relative density, hardness, and fracture toughness values of 98.5%, 2820 GPa, and 3.9 MPa.√m, respectively. Examination of SEM images showed that by increasing carbon from 0.5 to 2.5 wt%, the fracture changes from intergranular to transgranular.

“…However, the wear resistance of the silicon-based ceramics is challenged by the occurrence of the tribochemical reactions under complex operating environments in the real engineering applications ( Renz et al, 2016 ; Das et al, 2018 ; Schmidt et al, 2019 ; Yue et al, 2019 ). It has been reported that the wear of Si 3 N 4 and SiC ceramics against B 4 C balls can be suppressed in high RH conditions ( Figure 4A ) ( Cao et al, 2020 ) due to the formation of a tribo-film in the tribochemical reactions occurring especially during the running-in period ( Zum Gahr et al, 2001 ; Kovalčíková et al, 2014 ; Zhang et al, 2017 ). This mechanism that has been accepted broadly though the detailed structures of the tribo-film on the atomic scale is still unclear.…”

Tribochemical wear of contact materials is an important issue in science and engineering. Understanding the mechanisms of tribochemical wear at an atomic scale is favorable to avoid device failure, improve the durability of materials, and even achieve ultra-precision manufacturing. Hence, this article reviews some of the latest developments of tribochemical wear of typical materials at micro/nano-scale that are commonly used as solid lubricants, tribo-elements, or structural materials of the micro-electromechanical devices, focusing on their universal mechanisms based on the studies from experiments and numerical simulations. Particular focus is given to the fact that the friction-induced formation of interfacial bonding plays a critical role in the wear of frictional systems at the atomic scale.

“…On the other hand, for samples with longer anodization times, the peaks shifted to negative directions as shown in the figure. It has been understood that B atoms with small atom sizes occupy the interstitial positions more with the increase of anodization time [43][44][45].…”

Titanium and its alloys have many advantages such as acceptable biocompatibility and good corrosion resistance and these advantages make them a widely preferred biomaterial. However, it is also known that they have some disadvantages such as poor wear resistance and insufficient surface wettability. Therefore, to overcome this disadvantages, boric/sulfuric anodic films with different anodization time was formed on the surface of Ti6Al4V. The morphological and structural properties of anodic films were evaluated by XRD, XPS, SEM, Raman spectra, micro-hardness tester, 3D profilometer, and surface tension-meter. Also, the tribological behavior of them was analyzed by a pin-on-disk tribotester. The average coefficient of friction (CoF) of the untreated Ti6Al4V alloy is 0.37, while the CoF of boron containing TiO 2 anodic films is in the range of 0.04-0.15. Also, the anodic films reduced the wear rate by about 30% compared to the untreated Ti6Al4V. In addition to all these, it was observed that the anodic films changed the surface morphology. It was determined that the produced anodic films were in porous structures and with the increase of the applied anodizing time, the possibility of contacting the liquid with the surface increased.
