Abstract

A method of manufacturing a coated turbine vane () comprises manufacturing a turbine vane () having a platform () and an aerofoil () extending from the platform (), a curved transition () connects the platform () to the aerofoil () and a recess () is provided in the curved transition () from the platform () to the aerofoil (). A bond coating () is deposited on the platform (), the aerofoil (), the curved transition () and the recess (). A ceramic thermal barrier coating () is deposited on the platform (), the recess () and the curved transition () by plasma spraying. The recess () reduces the size of the step due to the ceramic thermal barrier coating () and hence improves the aerodynamics of the turbine vane ().
