Pandit, Ashwin S and Das, Siddhartha (2002) Plasma Sprayed Ceramic Coatings on Metallic Substrates. In: Proceedings of Seminar on Resurgence of Metallic Materials the Current Scenario (ROMM-2002), 24-25, October 2002, National Metallurgical Laboratory (CSIR), Jamshedpur.
Plasma spraying stands out as one of the most versatile and technologically sophisticated thermal technique in the field of surface engineering. Plasma sprayed ceramic coated components are used as wear resistant and as ther-mal barrier materials. The objective of the present work is to study the tribo-logical and thermal behaviour of different types of cera-mic coatings. Zircon and aluminazircon coatings are tried out on mild steel substrates with (Ni -Al and high carbon iron) bond coat and also without bond coat. The coatings have been characterized by XRD, SEM, Wear, Grindability and Thermal Fatigue successfully. The presence of mullite in the top coat has been found to be reponsible for the superior high temperature properties of the coating.
