COATING METHOD AND COVERING FOR REMOVING OVERSPRAY-ADHERENCES

摘要

The invention relates to a coating method wherein partial areas of a surface of a substrate are coated by thermal spraying. Said method comprises the following steps: (a) the substrate is coated in the partial areas which are provided for coating, whereby, at least one partial area which is not provided for the coating accumulates the overspray-adherences; (b) the coating is covered, in the partial area (good layer) which is provided for the coating, with a covering; (c) the overspray adherences are removed in the partial areas which are not provided for the covering and which are not covered with a cover, by means of a particle beam method for removing material. The danger of disturbing overspray adherences during thermal spraying is at least reduced during said coating method. For step (c), a covering is provided which can be arranged over the good layer, such that the good layer is protected by a particle beam when the overspray adherances are removed. Step (c) can be carried out in a simple manner with the covering. The invention also relates to a maintaining device for said type of covering.
