Abstract
A method of coating an inner surface of a tubular workpiece includes immersing the tubular workpiece lengthwise into a liquid subphase, inserting a first end of a delivery tube into the tubular workpiece so as to bring a distal end surface of the delivery tube to within a predetermined distance from the liquid surface, dispensing a suspension of coating particles into the first delivery tube to form a monolayer of the coating particles on the liquid surface in an area of the liquid surface between the inner surface of the tubular workpiece and an outer surface of the first delivery tube, and withdrawing at least a portion of the tubular workpiece from the liquid subphase so as to form a coating of the coating particles on a portion of the inner surface of the workpiece.
