Method for protecting silver and silver alloy surfaces against tarnishing |
| abstract |
A method for protecting silver and silver alloy surfaces against tarnishing, characterised by: - initially subjecting the surface to be treated to cleaning pre-treatment in organic solvents, - immersing the thus cleaned surface in an acid solution able to ensure formation of a thin layer of silver oxide, - immersing the thus oxidized surface in a solution of at least one thiol of formula CH 3 (CH 2 ) n SH where n is between 10 and 16, - chemically reacting the molecules of said thiol with the previously oxidized silver surface, in an environment containing water vapour at a temperature of at least 500C. |
