Abstract

The present disclosure relates to coating a carrier component by means of cold gas dynamic spraying. For example, a method for coating a carrier component may include: laying a mask with an opening on the component; depositing a material through the opening to completely fill up the mask opening; removing any material located above the upper side to form a flat surface even with the upper side of the mask; laying a second mask on the first mask; depositing the material again; removing any deposited material located above the upper side of the second mask to form a flat surface even with the upper side of the second mask; repeating layers of additional masks and material deposition until the deposited material reaches a required thickness on the carrier component; and after completion of the coating to the required thickness, removing the masks.
