Effect of Different Process Parameters & Analysis of Mechanical Properties of HVOF Sprayed Coatings on Stainless Steel Substrates

The advance in the field of materials science and particularly the development of functional coatings by different techniques of deposition in the solid state, has improved the efficiency and safety of components and equipment that are subject of extreme conditions involving high temperatures and pressures of operation such as: heat exchangers, boilers, furnaces, as well as (Aeronautics) gas turbines blades. Steam turbines represent an area of interest for the development of coatings that not only can resist high temperatures, but would also be capable of withstanding exposure to corrosive environments and wear. Hardness is also the main important property which important for the service life of coating. This upcoming dissertation will give us the mechanical properties of material with & without coated surface also this dissertation includes micro hardness test & erosion behaviour of coated material by fluctuating input parameters viz. Powder feed rate, stand-off distance, Fuel flow rate etc.
