Abstract
A method of closing a canal which has been formed in a wall of a component such as a heat exchanger for rocket combustion chamber walls comprises inserting an elongated filler into the canal so as to leave at least one end of the filler which projects out of the canal, filling the remaining space with an electrically conducting melting substance such as a wax, engaging the projecting end of the filler to pull it out of the substance in the canal and to leave the expanding chamber in the substance, an electroplating metalloplastic material onto the component to form a cover over the canal and the substance therein. Electroplating can be carried out without causing any heat which is produced thereby to affect an expansion in the canal which would disturb the electroplating or the formation of the component.
