Tribocorrosion behaviours of nickel (Ni) and niobium (Nb) in sodium sulfate (Na2SO4) solution under potentiodynamic potentiostatic conditions were studied. Under the condition, passivation was early broken, accompanied by a sharp increase frictional coefficient on Nb. The current more fluctuant, larger material loss appeared at higher potential condition. However, these phenomena did not occur ...

This study aims to investigate the improvement of tribocorrosion properties WC-TiC-Co substrates by coating them with hard coatings such as AlCrSiN using cathodic arc deposition. is commonly used in fabrication machining and cutting tools; however, there are some materials titanium or stainless steel that difficult work with; furthermore, aggressive environments under high temperatures performa...

In this study, the influence of high-pressure torsion (HPT) processing parameters and solution treatment (ST) on corrosion tribocorrosion behavior CoCrMo (CCM) alloys was investigated for possible usage in biomedical applications. The CCM by using potentiodynamic scanning (PDS) electrochemical impedance spectroscopy (EIS) tests. Tribocorrosion tests were carried out a reciprocating ball-on-plat...

Novel in-situ Ti-based matrix composites (TMCs) were developed through the reactive hot pressing of Ti + NbC powder blends. Due to chemical reaction that occurred in solid-state during processing, produced samples composed an Nb-rich β-Ti phase formed a metallic along with Ti2C as reinforcing phase. By employing different proportions Ti:NbC, composition alloys was designed contain ratios α-Ti a...
