Surface Engineering for Corrosion and Wear Resistance Application
ABOUT THE COURSE:
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.

ABOUT THE INSTRUCTOR:
Professor Manna is a renowned academician and prolific researcher with wide ranging research interests concerning microstructure-property-parameter correlation in nanometric and amorphous solids, laser and plasma assisted surface engineered components, bainitic and ODS steel and nano-fluid. His significant contribution in the study of amorphous/nanocrystalline Al-alloys, nano-fluid and laser/plasma assisted surface engineering received intense attention from the scientific community and is highly lauded. His early contributions in moving boundary phase transformation are still widely cited. Professor Manna has over 300 publications in peer reviewed journals and proceedings. He has supervised over 20 PhD theses. While serving in the Metallurgical and Materials Engineering Department at IIT Kharagpur, Professor Manna developed several new research laboratories and facilities like plasma ion implantation and coating unit (DST, Tata Steel), Mechanical Alloying laboratory (DST, CSIR), Wear and erosion testing laboratory (CSIR, Tata Steel, DST), Electron bean joining facility (BRNS), Pulsed laser deposition and FE-SEM laboratory (DST), Nanofluid synthesis and characterization laboratory (ISRO), etc.
Prof. Dutta Majumdar is well known internationally for her research contribution in the field of Metallurgical and Material Engineering with focus on surface engineering and laser surface processing. She made fundamental contributions to a profound understanding of the metallurgy of rapid solidification of metals under the specific heat input of a laser source. Her works also concern a detailed structure-property correlation of laser surface modified metallic materials with a specific goal to improve certain engineering properties. She also stated a brief understanding of the mechanism of wear, corrosion and high temperature oxidation of the metastable microstructures developed in commercial metals and alloys due to laser processing. Extensive efforts were also made for the first time for the development of compositionally graded surface and nano-dispersed surface for thermal barrier and hot corrosion application by application of hybrid coating technology.
