COATING METALLIC MATERIAL ; COATING MATERIAL WITH METALLIC MATERIAL ; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION ; COATING BY VACUUM EVAPORATION, BY SPUTTERING, BY ION IMPLANTATION OR BY CHEMICAL VAPOUR DEPOSITION, IN GENERAL( applying liquids or other fluent materials to surfaces in general B05; making metal-coated products by extrusion B21C 23/22 ; covering with metal by connecting pre-existing layers to articles, see the relevant places, e.g. B21D 39/00 , B23K; working of metal by the action of a high concentration of electric current on a workpiece using an electrode B23H; metallising of glass C03C; metallising mortars, concrete, artificial stone, ceramics or natural stone C04B 41/00 ; paints varnishes, laquers C09D; enamelling of, or applying a vitreous layer to, metals C23D; inhibiting corrosion of metallic material or incrustation in general C23F; single-crystal film growth C30B; manufacture of semiconductor devices H01L; manufacture of printed circuits H05K )
NOTE
-
In this subclass, an operation is considered as pre-treatment or after-treatment when it is specially adapted for, but quite distinct from, the coating process concerned and constitutes an independent operation. If an operation results in the formation of a permanent sub- or upper layer, it is not considered as pre-treatment or after-treatment and is classified as a multi-coating process.

WARNING
-
1. Groups C23C 28/30 to C23C 28/44 do not correspond to former or current IPC-groups. Concordance CPC : IPC for these groups is as follows - C23C 28/30 - 28/44 : C23C 28/00


The following IPC groups are not used in the CPC system. Subject matter covered by these groups is classified in the following CPC groups:
C23C14/36 to C23C14/44 covered by C23C 14/34 + subgr.
