DETAILED DESCRIPTION SHORT COURSE ON …

1 DETAILEDDESCRIPTIONSHORT COURSE ONCHEMISTRY,PHYSICS ANDMECHANICS OFADHESION SCIENCEA dhesion plays an important role in many technologies and industries, viz., automotive, thin films, optics, coatings,paint and so on. Broadly speaking, the topic can be divided into two categories: film or coating /substratecombination, and adhesive joint. Films and coating are used for a variety of purposes and irrespective of theirintended function, these must adhere adequately to the underlying substrate. So the need for understanding andcontrolling the factors affecting adhesion is quite patent. Also the durability of the bond (on exposure to processchemicals, moisture, corrosives, etc.) is of grave concern and importance. This COURSE presents an overview of the chemistry , physics and mechanics of adhesion in regard to understanding fundamental adhesion mechanisms, howto improve and control them and the latest adhesion measurement techniques which are being used to evaluate thePRACTICAL ADHESION of coatings and laminate structures.

2 Emphasis is given to methods which can be carriedout in a manufacturing environment as well as in the lab and which give results that are directly relevant to thedurability and performance of the structures under investigation. The effects of coating elastic properties andresidual stress are considered as well as other external influences which affect durability under use conditions. Finally, an overview of the impact of atomic and molecular interactions on micrometer and nanometer sizedstructures (Micro-Electro Mechanical Systems - MEMS and Nano Electro Mechanical Systems- NEMS) will beexplored. This leads to an elementary discussion of the most fundamental aspects of atomic and intermolecularbehavior involving the concepts of quantum : Scientists and professional staff in R&D,manufacturing, processing, quality control/reliabilityinvolved with adhesion aspects of coatings and adhesionsensitive : Beginner- Intermediate introduction/overviewPrerequisites: Elementary background In chemistry ,physics or materials : 3 daysCourse materials: complete set of lecture notes pluscopy of the handbook, study supplement and referenceguide ADHESION MEASUREMENT METHODS:THEORY AND PRACTICE, (CRC PRESS, 2006)WHAT ARE YOU TAUGHT AND HOW YOU WILLBENEFIT FROM THIS COURSE :After completing this COURSE , you should be able to.
