Cold gas dynamic spraying using a mask

A method for coating a carrier component with cold gas dynamic spraying, the method comprising:

• laying a first mask with a first opening upon the carrier component;
• depositing a material through the first opening of the first mask onto the carrier component;
• after deposition of the material, removing any deposited material located above a level of an upper side of the first mask forming a flat surface in the region of the first opening even with the level of the upper side of the first mask;
• determining whether the sprayed surface inside the first opening of the first mask aligns with the upper side of the first mask and, if not, depositing additional material through the first opening;
• laying a second mask with a second opening on the upper side of the first mask;
• depositing the material upon the material previously deposited;
• after deposition of the material through the second mask, removing any deposited material located above a level of the upper side of the second mask forming a flat surface in the region of the second opening even with the level of the upper side of the second mask;
• determining whether the sprayed surface inside the second opening of the second mask aligns with the upper side of the second mask and, if not, depositing additional material through the second opening;
• repeating layers of additional masks and material deposition until the deposited material reaches a required thickness on the carrier component;
• and
• after the deposited material reaches the required thickness, removing the masks and leaving a coating in place;
• wherein at least one of the masks comprises a multiplicity of parts, and parting lines extend from an outer edge of the mask to the respective mask opening so that the multiplicity of parts can be pulled apart in a direction parallel to their upper side and reused in later material deposition processes.
