Turbine blades used in commercial aviation require very close tolerances in order to maintain engine performance. Blade tip clearances and shroud gap limits are held to within several thousandths, keeping air bypasses and vibration to a minimum. At both the maintenance and overhaul levels, components are inspected to serviceable guidelines and turbine blades that exceed acceptable service limits were, until recently, removed and tagged unserviceable or discarded. Laser cladding offers a cost saving alternative to the replacement of unserviceable turbine blades. With today`s automation systems and an effective quality control procedure in place this process can produce acceptable yields.
