In this paper, Fly-ash+quartz+illmenite with weight percentage ratio: 60:20:20, is deposited on mild steel and copper substrates by atmospheric plasma spraying at various operating power level ranging from 11 to 21 kW. The properties of the coating depend on the interaction of coating powder with plasma, operating condition and the process parameters. The coating quality and behavior depends on Coating surface & interface morphology are studied with Scanning Electron Microscope. For Mild Steel the adhesion strength has varied from 3.5MPa to 6.56MPa and for Mild steel a maximum of 6.56MPa at the power level of 21 kW. In plasma spraying, …
Improvement Of Mild Steel Surface Properties By Fly-Ash + Quartz + Illmenite Composite Coating, Ajit Behera

Plasma spray of fly-ash composite gives a stable improvement of surface properties for industrially used materials/equipments, which has become a major technological research area encompassing studies in a broad range from medical field, chemical field to ceramic field. In the present investigation, coatings are developed on mild steel substrates using fly-ash + quartz + illmenite composite (in a weight percentage ratio of 60:20:20) at various plasma torch input power levels ranging from 11 to 21 kW DC. Metallographic and chemical characterization of the produced composite coatings was performed with the aid of scanning electron microscopy (SEM) and XRD analysis. The …
