Abstract:
A method of forming at least one coating layer containing at least one of a metal and a ceramic on an inner wall surface of a hollow body, comprising the following steps:a) arranging said hollow body in a deposition chamber;b) arranging a target of at least one target material comprising at least one of a metal and a ceramic in said deposition chamber;c) creating a reduced pressure within said deposition chamber;d) providing a controlled residual gas atmosphere within said deposition chamber;e) directing a pulsed laser beam to impinge on said target, vaporize a portion of said target material and form a plasma of said vaporized target material in said deposition chamber;f) condensing said plasma and depositing said target material from said plasma onto an area of an inner wall surface of said hollow body to form at least one coating layer comprising said target material on said area of said inner wall surface; andg) simultaneously directing an auxiliary laser beam to impinge onto said coating layer that is being formed or has previously been formed on said inner wall surface.
