Abstract The formation of tribochemical reaction layers, better known as tribofilms, on cobalt-chromium-molybdenum (CoCrMo) alloys commonly used in orthopaedic applications has been hypothesized to reduce degradation owing wear and corrosion. However, the mechanisms pathways influencing tribofilm remain largely unknown. This study aims develop a clearer understanding role protein structures its...

CoCrMo alloys are used in hip and knee replacements due to their excellent long-term survival rates. However, high failure rates have recently been observed associated with adverse tissue reactions. alloy surfaces undergo microstructural changes during wear, including the formation of ?-martensite and, occasionally, a nanocrystalline surface layer. It is not clear whether these beneficial or de...

In this paper, four ionic liquids based on chromotropate (CAILs) were prepared and applied to heighten the tribological performance of aqueous system different metal friction contacts. Taking for potential choice water-based lubricating additive, CAILs exhibited excellent water solubility corrosion resistance. Tribological results showed that CAILs, especially phenolic hydroxyl group decorated ...
