Mishra, S C and Mishra, P C and Rout , K C and Anantapadmanabahn, P V (1999) Fly ash as a coating material for plasma spray coatings. In: Proceedings of the National Seminar on Fly Ash Utilisation, February 26-27, 1999, NML Jamshedpur, India.
The present piece of work has been undertaken to use fly-ash in developing plasma spray coatings on metal substrates. Fly-ash and fly-ash with 5% alumminum metal powder were (premixed thoroughly) plasma sprayed on stainless steel and aluminum substrates at various operating power levels of plasma torch. The coating thus produced, was characterized by thickness measurement, X-ray diffraction analysis, microscopic studies and measurement of coating-substrate adherence strength. X-ray analysis reveals the presence of alumina, silica and mullite phases. The adherence strength seems to increase with aluminum addition to flyash.
