C23C 22/12

containing zinc cations

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Chemical surface treatment of metallic material by reaction of the surface with a reactive liquid, leaving reaction products of surface material in the coating, e.g. conversion coatings, passivation of metals > using aqueous solutions > using aqueous acidic solutions with pH < 6 > containing phosphates > Orthophosphates > containing zinc cations

CPC:

Chemical surface treatment of metallic material by reaction of the surface with a reactive liquid, leaving reaction products of surface material in the coating, e.g. conversion coatings, passivation of metals > using aqueous solutions > using aqueous acidic solutions with pH less than 6 > containing phosphates > Orthophosphates > containing zinc cations

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

IPC defines codes here since 1985.
