Abstract
The invention relates to a method for removing an area of a layer of a component consisting of metal or a metal compound. According to prior art, corrosion products of a component are removed in a first step by applying a molten mass or by heating in a voluminous powder bed. This requires high temperatures or a large amount of space. The inventive method for removing corrosion products of a component is characterized in that a cleaning agent is applied locally, which removes the corrosion products by means of a gaseous reaction product.
