Study the Fatigue Corrosion Behavior of Turbine Blade by Laser Cladding

Abstract:

The turbine blades utilized in this investigation were made of alloy steel type 52, the same steel used in electric power plants. The current research aims to study the effect of corrosion fatigue behavior on turbine blades when cyclic loads and corrosion work together to degrade a material's mechanical properties. As a result, many engineering structures and components experience early failure. Laser cladding is a method of laser surfacing to improve or rejuvenate the surface of an object. This parameter was used in the cladding process. 132 watts of laser power, with a peak output of 1.83 kilowatts, was used to generate the pulses, with each pulse containing 11 joules of energy. The results reveal that the specimen's microstructure is smoother following the laser cladding procedure and that the corrosion fatigue resistance in the air (without solution) is increased. This paper will look at how laser cladding impacts turbine blades.
