Woodhead Publishing Tribocorrosion of Passive Metals and Coatings (Woodhead Publishing Series in Metals and Surface Engineering)

Metals can become less reactive to corrosion processes (i.e. they become passive) because of protection by a self-healing surface film. This passivation process is an important weapon against corrosion in metals. However, the corrosion resistance of passive metals can be substantially reduced by friction and wear. This important book reviews current research on tribocorrosion of passive metals and coatings. Key Features: comprehensively reviews current research on the tribocorrosion of passive metals and coatings, with particular reference to the design of tribocorrosion test equipment, data evaluation and the optimisation of materials properties for tribocorrosion systems; chapters discuss tribocorrosion mechanisms under fretting, sliding and erosion conditions before focussing on methods for measuring and preventing tribocorrosion; includes a comprehensive selection of tribocorrosion problems in engineering and medicine, such as the tribocorrosion of medical implants, and tribocorrosion issues in nuclear power plants, marine environments, automotive cooling circuits and elevated-temperature metal working. Contents: Part 1 Fundamentals of tribocorrosion: Corrosion and passivity of metals and coatings; Adsorption layers and passive oxide films on metals; Friction and wear of passive metals and coatings; Environmental effects in fretting; Tribocorrosion mechanisms in sliding contacts; Models and mechanisms of erosion corrosion in metals. Part 2 Methods for measurement and prevention of tribocorrosion: Electrochemical methods in tribocorrosion; Tribocorrosion test protocols for sliding contacts; Methods for studying erosion-corrosion; Metallic materials for tribocorrosion systems; Coatings for tribocorrosion protection. Part 3 Tribocorrosion in engineering and medicine: Biotribocorrosion: surface interactions in total joint replacement (TJR); Tribocorrosion in artificial joints: in vitro testing and clinical implications; Fretting corrosion in biomedical implants; Tribocorrosion issues in nuclear power generation; Tribocorrosion in marine environments; Erosion-accelerated corrosion in flow systems: the behaviour of aluminium alloys in automotive cooling systems; Chemical-mechanical polishing (CMP): a controlled tribocorrosion process; Tribocorrosion at elevated-temperatures in the metal working industry.
