Corrosion, Damage and Wear (MATS 704)
Offered By:
Engineering and Materials Science Faculty
Description
Short review of deformation behavior, damage mechanisms and failure mode of materials under service like loading (yield, creep, strain or stress controlled fatigue, creep-fatigue interaction). Damage influence parameters (temperature, time, environment, load rate, material state and metallurgical aspects) Damage Tribology, fundamentals of friction, wear and lubrication, system analysis, types of wear, wear appearances, wear mechanisms, boundary surface processes, sliding wear of metals, polymers and ceramics, lubrication states, reaction layer formation, “flash temperature”, rolling processes, fretting ,abrasive wear, erosion, cavitation, Wear and wear testing Wear simulation, wear resistant materials, wear measurement techniques, pin-on-disc test. Corrosion Kinetics of electrochemical corrosion, corrosion in systems with a low conductivity, electrochemical corrosion, types of electrochemical corrosion. Corrosion of metals Iron and steels, nickel and nickel alloys, copper and copper alloys, aluminum and aluminum alloys, magnesium and magnesium alloys, zinc and zinc alloys, titanium and titanium alloys. Corrosion of polymers Relation between the chemical composition and the chemical-physical behavior of organic polymers, corrosion processes and aging of polymers Corrosion testing Corrosion tests, execution of corrosion tests, tests under laboratory conditions, electrochemical corrosion tests. Active protection against corrosion Protection by design, inhibitors, electrochemical protection. Passive protection against corrosion non permanent protection, metallic and non metallic coatings, organic coatings, environment protection.
