REVIEW ON THE SPRAYING PROCESS IN THERMAL POWER PLANTS

A coating may be a covering method that's applied to the surface of a fabric that is referred to because the substrate. The coating itself is either utterly coated through the total surface or the particular elements of the substrate. Thermal spray coating is one in every of the foremost effective ways to shield the new elements from wear, high temperature corrosion, residual stresses, erosion, and to produce exhausting and dense coatings, therefore life of material is multiplied. during this method, comparatively thick gilded, polymer, ceramic and composite coatings is deposited. The optimum coating method is chosen on the idea of desired coating properties. Coating material is either within the type of wire, powder, rod, wire or molten-bath kind. The procedure is manual, mechanized or absolutely machine-driven. This paper reviews the previous research in the sector of thermal spray coating.
