Electropolishing in organic solutions

Abstract

Electrolyte for electropolishing metal parts, where electrolyte consist of non-hazardous organic as dissolvent and metal salts of the same metal that is to be polished. Such electrolyte can be used for electropolishing stainless steel of various alloy types. Another variation of electrolyte based on non-hazardous organic as dissolvent, is used to electropolish titanium, zirconium, hafnium, tantalum, niobium, molybdenum, and their alloy, for example nitinol. Such electrolyte include potassium, sodium, lithium, or ammonium salts of fluoride-containing salts.

1 . Electrolyte for electropolishing metal parts, comprising water and/or organic dissolvent and metal salts, of the same metal that is to be polished.  
   
   
       2 . Electrolyte for electropolishing titanium, zirconium, hafnium, tantalum, niobium, molybdenum, and their alloy, which comprise organic dissolvent and potassium, sodium, lithium or ammonium salts of fluoride-containing salts.  
   
   
       3 . Electrolyte from  claim 1  and  2  where organic dissolvent is selected from a group of non-hazardous organics.
