Role of nanomaterials on tribocorrosion

Tribocorrosion is the degradation of materials caused by simultaneous mechanical and chemical/electrochemical interactions between surfaces in relative motion, resulting in irreversible transformation of materials or of their functions. The present chapter addresses the role of nanomaterials on tribocorrosion. It focuses on the ability of nanoparticles in providing a lubricating effect and the usefulness of nanostructured coatings such as, thermally sprayed FeCu/WC-Co and WC-Co coatings, electrodeposited Ni-Co alloy, Ni-nano SiC, electroless Ni-P-nano SiC coatings, and, nanostructured titanium, in improving the tribocorrosion performance of materials. The limitations of using nanoparticles and nanostructured coatings under tribocorrosion conditions are also addressed.
