       12 . A process for an electrolytic treatment of a component having at least two through-holes, comprising:
 treating the through-holes on a inner surface;   
     using a separate pole electrode for each through-hole to be treated, wherein the separate pole electrodes are of identical polarity, and wherein at least two pole electrodes are of a different shape; and
 pulsing an electric voltage present across the component as a pole counterelectrode and the pole electrodes. 
 
   
   
       13 . The process as claimed in  claim 12 , wherein the treating of the at least two through-holes is a coating. 
   
   
       14 . The process as claimed in  claim 12 , wherein during the treatment an electrolyte flows through the through-holes. 
   
   
       15 . The process as claimed in  claim 14 , wherein the electrolyte flows from an inside outward, out of a cavity to treated an inner surface of the through-holes. 
   
   
       16 . The process as claimed in  claim 12 , wherein a through-hole is made via an EDM electrode, and wherein the EDM electrode is used as a pole electrode for the electrolytic process. 
   
   
       17 . The process as claimed in  claim 12 , wherein the pole electrode is arranged outside a hollow component. 
   
   
       18 . The process as claimed in  claim 12 , wherein a time-dependent flow of an electrolyte through at least one through-hole is measured, and wherein the progress of the internal coating of the through-hole is determined based upon the flow. 
   
   
       19 . The process as claimed in  claim 12 , wherein the component is arranged in an electrolyte, and wherein a further electrolyte flows through the through-holes. 
   
   
       20 . The process as claimed in  claim 19 , wherein the further electrolyte has a different chemical composition than a material for the coating. 
   
   
       21 . The process as claimed in  claim 19 , wherein the further electrolyte has a different concentration than a material for the coating. 
   
   
       22 . The process as claimed in  claim 12 , wherein only the inner surface is coated. 
   
   
       23 . The process as claimed in  claim 12 , wherein only the inner surface and an internal surface of the component are coated. 
   
   
       24 . The process as claimed in  claim 12 , wherein only the inner surface and an external surface of the component are coated. 
   
   
       25 . The process as claimed in  claim 12 , wherein the component is a turbinde blade of a gas turbine. 
   
   
       26 . A turbine blade of a gas turbine, comprising:
 through-holes treated based upon an pulsed electrolytic treatment.
