Surface Engineering for Corrosion and Wear Resistance Application

Surface Engineering for Corrosion and Wear Resistance Application. Instructors: Prof. Indranil Manna and Prof. Jyotsna Dutta Majumdar, Department of Metallurgical and Materials Engineering, IIT Kharagpur. Wear and corrosion are the major causes of degradation of engineering components for structural applications. Among different ways of minimizing the probability of failure of components by wear or corrosion or improving its lifetime is by optimum designing of surface, may be termed as surface engineering. However, the properties achieved on the surface depend on the techniques to be applied, process parameters to be chosen and the surface characteristics (surface roughness, microstructure and composition) achieved thereafter. The present course encompasses (a) a brief introduction to the wear and corrosion and their classification, (b) surface microstructure and composition required for combating different modes of wear and corrosion, (c) classification and scopes of surface engineering, (d) principle of different modes of surface engineering, process parameters, advantages and disadvantages, (e) characterization and testing of surfaces and (f) engineering applications of surface engineering techniques. The course will offer training to the engineering students pursuing studies in the UG and PG level from Metallurgical engineering, mechanical engineering, materials science, physics and chemistry.
