| Description |
MgO-Al(2)O(3)-TiO(2) based glass ceramic coatings were formed on nimonic superalloy substrates by microwave and conventional heat treatment processes. The resultant glass ceramic coatings were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), image analysis, nanohardness and Young's modulus evaluation by depth sensitive indentation (DSI) technique. Nanohardness and Young's modulus values of the microwave heat treated glass ceramic coatings were improved in comparison to those of the conventionally treated glass ceramic coatings due to presence of finer sized crystallites in the microwave processed coatings. Slight enhancement in the nanohardness and Young's modulus values with soaking time for the microwave processed coatings were explained in terms of the microstructural refinement and the reinforcement of the parent glass matrix.
