Glass and glass-ceramic coatings, versatile materials for industrial and engineering applications

Among various coating systems for industrial and engineering applications, glass and glass-ceramic coatings have advantages of chemical inertness, hig h temperature stability and superior mechanical properties such as abrasion , impact etc as compared to other coating materials applied by thermal spra ying in its different forms viz. PVD, CVD, plasma, etc. Besides imparting r equired functional properties such as heat, abrasion and corrosion resistan ce to suit particular end use requirements, the glass and glass-ceramic coa tings in general also provide good adherence, defect free surface and refra ctoriness. Systematic studies covering the basic science of glass and glass-ceramic co atings, the functional properties required for a particular end-use along w ith the various fields of application have been reviewed in this paper.
