Abstract:
1. A method for applying at least one coating on at least one substrate, said method comprising: presenting a stationary substrate to a chamber; said chamber having a downstream pressure, Pc, with an operating range from about 10 presenting at least one evaporant source to said chamber; presenting primary carrier gas streams comprised of gas molecules to said chamber; impinging at least one said evaporant source with at least one energetic beam in said chamber to generate an evaporated vapor flux comprised of evaporant molecules; said substrate having a distal end and a proximal end defining a longitudinal section therebetween, said substrate having an interior cavity; and said primary carrier gas streams deflecting at least a portion of said generated evaporated vapor flux by said primary carrier gas streams from an area distal from and external to said stationary substrate into said interior cavity of said substrate thereby coating at least a portion of interior of said longitudinal section.
