摘要

Method for treating a mask used in thermal coating of cylinder bores in engine blocks comprises inserting an activation mask (1) with at least one bore (2.1 - 2.3) through its walls. This allows small areas of the inner surface of the main mask to be activated to improve adhesion while the remainder remains unchanged.
