Claim 15:
16. The method of claim 9, wherein the ceramic coated metallic article is the turbine vane segment, the first portion of the metallic article comprises the plurality of aerofoils of the turbine vane segment and the second portion of the metallic article comprises the first and second platforms of the turbine vane segment, and
wherein step e) comprises traversing the nozzle in a first pass over a convex surface of each aerofoil of the turbine vane segment from a trailing edge to a leading edge of each aerofoil adjacent to the first platform of the turbine vane segment, traversing the nozzle in a second pass over the convex surface of each aerofoil of the turbine vane segment from the trailing edge to the leading edge of each aerofoil adjacent to the second platform of the turbine vane segment, traversing the nozzle repeatedly back and forth over the convex surface of each aerofoil of the turbine vane segment 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 leading edge and the trailing edge of each aerofoil.
