Use of sulfonic acids in dry electrolytes to remove vapor deposited and/or thermally sprayed coatings on metal surfaces

Abstract

The use of dry electrolytes to strip vapor or thermal spray deposition coated metal surfaces through ion transport, wherein the conductive liquid of the dry electrolyte comprises at least a sulfonic acid.

What is claimed is: 
     
         1 .- 12 . (canceled) 
     
     
         13 . A method of stripping a vapor or thermal spray deposition coated metal surface through ion transport, the method comprising contacting the metal surface with a conductive liquid of a dry electrolyte, wherein the conductive liquid comprises at least a sulfonic acid 
     
     
         14 . The method of  claim 13 , wherein the dry electrolyte comprises porous particles. 
     
     
         15 . The method of  claim 14 , wherein the porous particles comprise a sulfonate polymer. 
     
     
         16 . The method of  claim 14 , wherein the porous particles comprise an ion exchange resins of polystyrene-divinylbenzene. 
     
     
         17 . The method of  claim 13 , wherein the sulfonic acid comprises methane-sulfonic acid. 
     
     
         18 . The method of  claim 13 , wherein the concentration of sulfonic acid in relation to a solvent is from 1% to 70%. 
     
     
         19 . The method of  claim 13 , wherein the conductive liquid further comprises a complexing agent. 
     
     
         20 . The method of  claim 19 , wherein the wherein the complexing agent comprises a polyether. 
     
     
         21 . The method of  claim 20 , wherein the wherein the polyether is linear alkyl. 
     
     
         22 . The method of  claim 21 , wherein the wherein the polyether is polyethyleneglycol. 
     
     
         23 . The method according to  claim 22 , wherein the polyethyleneglycol has a molecular weight ranging from 200 to 500 Da. 
     
     
         24 . The method of  claim 21 , wherein the wherein the polyether is polypropyleneglycol. 
     
     
         25 . The method of  claim 13 , wherein the conductive liquid further comprises a chelating agent.
