Abstract

Statement of the Problem: Ceramics possess high-temperature strength, high hardness, superior wear resistance, chemical stability, lower thermal and electrical conductivity. Glass-ceramics are prepared by controlled nucleation and crystallization of a glass precursor. The properties of glass-ceramics depend on its composition and microstructure, which are influenced by the processing technique. It has been already established that the microwave energy can be used for the processing of various materials on account of its unique microstructure and properties, improved product yield, energy savings, reduction in manufacturing cost and synthesis of new materials. The purpose of the present study was to form improved glass-ceramic coatings on metallic and ceramic substrates by using microwave processing technique.
