| Abstract: | Through plasma spray technology, it is possible to develop metallic and ceramic coatings on a wide
range of substrates and it also has the advantage of being able to process various low grade ore
minerals and wastes to obtain value added products like near-homogeneous coatings of desired
microstructure. Fly ash is such an industrial waste which is produced in huge quantities during power generation in a coal based power plants. The chemical analysis of fly ash indicates its tremendous potential to be used as a coating material on structural and engineering components, which are generally used in aggressive environments. In view of this, the present work describes the development and characterization of a new class of coatings made of fly ash pre-mixed with aluminium (Al) powder in different weight proportions (0, 5, 10, 15, 20, 25 and 30 wt%) on mild steel substrates by atmospheric plasma spraying route. The coating depositions are made at different torch input power levels ranging ... |
