The duty of air compressor in a gas turbine is to supply air for combustion and spine the pressure turbine. In frame type turbine many failure and wide range of damages have been reported in all of the world. Disruption of one blade can heavily damage the other components and a shutdown cause in the gas turbine which can impose many other costs to the system. Metallurgical and finite element investigations of damaged blades of second stage of compressor in the frame type gas turbine in one of occurred in an on–shore gas complex, showed high cycle fatigue (HCF) and foreign object damages (FOD) which was the result of separation of a piece of a blade and clashing with other blades, were main reasons of failure<\div>

Nowadays, high velocity HVOF (High–Velocity–Oxygen–Fuel) coating is one of the newest and advanced method to coat which uses fuel and oxygen with special ratio and stick the coat on the substrate. The purpose of this research is investigation of the effect of thermal stress as result of thermal cycling in sprayed WC–Co coat with HVOF method on the 17–4PH steel. Observation of microstructure in SEM pictures showed that we had a good penetrated of coating on the substrate. Thermal cycling tests were performed at the temperature range between 100~600 oC without external load. Thermal residual stresses determined by using ANSYS software. The results showed that tensile stresses were more than compresses stress and mechanical properties of the coating layer for horizontal direction were bigger than for vertical direction.<\div>
