Abstract
A method for treating a metal material to make a surface portion hydrophobic. The method includes oxidizing an untreated surface portion of the metal material to form an oxidized surface portion. The untreated surface portion has metal atoms. The oxidizing step forming bonds between the metal atoms and oxygen atoms. The method further includes doping the oxidized surface portion with a liquid containing a fluorine-containing salt to form a fluorinated surface portion. The doping step forming bonds between fluorine atoms and at least a portion of the metal atoms and the oxygen atoms. The fluorinated surface portion is hydrophobic.
