Plasma spraying of an indigenous yttria stabilized zirconia powder prepared by the sol-gel technique
S V Joshi M P Srivastava M Chatterjee J Ray A Chatterjee D Ganguli
An indigenous sol-gel derived yttria-partially stabilized zirconia (Y-PSZ) powder has been characterized and its suitability for plasma spraying applications evaluated. The powder, determined to have about 5·1% yttria content, predominantly consisted of spherical particles with an average equivalent particle diameter close to 25
µ m. Furthermore, it was found that the powder did not contain any particles >50µ m, which is considered the ideal upper size limit for spray-grade ceramic powders in order to ensure complete melting during spraying. The sol-gel produced powder exhibited good flow characteristics and the plasma sprayed coatings developed using this powder were also found to have excellent thermal shock resistance. The corresponding results obtained using an imported Y-PSZ powder are also presented for the purpose of comparison. -

Synthesis of aluminium matrix composites containing nanocrystalline oxide phases
S K Pradhan A Datta A Chatterjee M De D Chakravorty
Using nanocrystalline particles of mullite and zirconia respectively with diameters in the range 20–30 nm prepared by a sol-gel route, aluminium metal-matrix composites have been synthesized. A hot pressing technique has been used with temperatures varying from 450–610°C. The vickers hardness values for the composites are found to be substantially higher than that of pure aluminium. An order of magnitude increase in hardness is achieved when Al5Mo phase is grown in the composite.
