<p>A method and an apparatus for producing a thermal barrier coating system for a substrate comprising a bond coat adhering to said substrate, a top layer adhering to said bond coat and said top layer having a microstructure comprises at least one zig-zag segment. The method comprises providing said substrate (10) in a deposition chamber (12); impinging an evaporant source (18) with an electron beam (13) generated from an electron beam gun (14) to form an evaporant; entraining said evaporant in a carrier gas (20) to form a flow of evaporant; and depositing said evaporant onto said substrate to form said top layer, wherein during the deposition said substrate is rotated by a device (22) so that varying the angle of the incidence of the flow on the substrate.</p> |
