Claim 10:
11. The method of claim 9, wherein the ceramic coated metallic article is the turbine vane, the first portion of the metallic article comprises the aerofoil of the turbine vane and the second portion of the metallic article comprises the first and second platforms of the turbine vane, and
wherein step e) comprises traversing the nozzle in a first pass over a concave surface of the aerofoil of the turbine vane from a first edge to a second edge of the aerofoil adjacent to the first platform of the turbine vane, traversing the nozzle in a second pass over the concave surface of the aerofoil of the turbine vane from the second edge to the first edge of the aerofoil adjacent to the second platform of the turbine vane, traversing the nozzle repeatedly back and forth over the concave surface of the aerofoil of the turbine vane in a direction between the first and second platforms between the first pass and the second pass with the back and forth traverses spaced apart in a direction between the first edge and the second edge of the aerofoil.
