Abstract

A procedure is described for a rust-proofing surface treatment of steel parts, especially for vehicle filter parts or components. This procedure consists of phases of washing, preheating, nitriding and steam oxidation of the batch to treat which takes on a black colouring as a result of the magnetite generated by the process. This process is also characterised by the particular composition of the gaseous nitriding atmosphere. The end products have high resistance to wear and corrosion. Two embodiments of the machine required for carrying out the procedure are also described. <IMAGE>
