ABSTRACT:
A surface protection for a hot-tinning system or soldering system particularly useful for the air jets of the system characterized by the surfaces of the parts, which come into contact with the solder during the process, being provided with a non-metallic, heat resistant layer. The layer, which preferably has a thickness range of between 0.2 and 0.4 mm, may be an Al.sub.2 O.sub.3 ceramic layer, which is preferably applied by a plasma spraying process, or may be a polytetrafluoroethylene coating. It is further desireable that the surface, which is to be protected by the heat resistant layer, is provided as a sand blasted surface which has been provided with an adhesion layer consisting of Ni-Mo-Al alloy.
