Poor tribocorrosion resistance of Ti and its alloys remains as a concern for load-bearing biomedical implants. Despite being an effective method to improve resistance, titanium matrix composites (TMCs) have yet be used in this type applications. In-situ TiB (titanium boride) TiC carbide) reinforcement phases been considered one the best options produce TMCs once these present high compatibility...

Abstract Ionic liquids have been widely discussed as potential lubricants, however, their properties make them also very good candidates lubricant additives (e.g., friction modifiers and anti-wear). In this work, the tribological study of two ionic (tributylmethylphosphonium dimethylphosphate (PP), 1-butyl-1-methylpyrrolidinium tris(pentafluoroethyl)trifluorophosphate (BMP)) has performed on st...

The aim of the article was to identify effect material hardness on tribocorrosion process by comparing two solutions. analysis concerned assessment intensity and identification mechanisms responsible for loss. Possible common materials high were determined. Two classic solutions (based AISI 1045 steel) ensuring subsurface layers tested: nitriding with an additional oxidation impregnation proces...

The introduction of modular design in total hip arthroplasty has enabled the use different materials one single configuration and adjustment prosthesis to patient’s body, facilitated medical revisions. However, modularity leads presence new interfaces created between pieces contact, raising issue degradation. Tribocorrosion phenomena have been identified as main degradation mechanism due mechan...
