Abstract
Non Destructive Evaluation of mechanical component like blade of rotating machine like turbine ensures the reliability of performance based on in-service degradation of component under operating condition and pre-service quality of component. Critical rotating components of Steam Turbine of power plants like Turbine blade are subjected to various stresses during operation, start–up and shut-down condition. These cause the components to undergoes cracks in the turbine blade at maximum concentration area. Hence the Non Destructive Inspection is carried out periodically for the prevention of failures of turbine blade due to probable cracks. These Fractures, cracks are generally reveled using Dye Penetrant Inspection Technique.
