Abstract
A method for spray forming a metal component (11, 17, 21, 27) having an elongated open channel (10, 20, 22, 28) therein comprises firstly spray forming a layer (8, 19, 24) of the desired metal onto a deposition substrate (2), placing then an elongated spray blocking object (9, 18, 26, 29) on the already sprayed layer for forming the channel, and continuing then the spray forming process until the desired total thickness of the component is achieved. According to the present invention, the spray blocking object is a strip (18, 26, 29), the cross-sectional profile of the strip being fully open in the direction of an axis (a) in a cross-sectional plane of the strip, and the strip is placed on the already deposited layer (8, 19, 24) with said axis directed substantially parallel to the direction of the incident metal spray (6).
