1. A method for coating a component of a turbomachine in a bath, comprising the steps of:
i) partially immersing the component in the bath containing a coating material;
ii) rotating the component at least intermittently around an axis of rotation, which lies outside of the bath, during the at least partial immersion; the component having a radially inner region proximal to the axis of rotation and a radially outer region distal to the axis of rotation;
iii) immersing the radially outer region of the component at most partially; and
wherein the coating serves as a mask in a subsequent processing of the component and is removed after subsequent processing.
