A method for manufacturing a ceramic-like music instrument comprises the steps of selecting a metal or metal alloy as a substrate of a music instrument; placing an auxiliary electrode in liquid; applied a voltage to a surface of the substrate and the auxiliary electrode so as to generate electric arc; the arc will gasify or ionize electrolyte nearby to generate plasma and thus generate an oxidizing film on the surface of the substrate,, wherein the oxidizing film is a ceramic like material. The electric arc generated on the surface of the substrate generates plasma so as to oxidize the auxiliary electrode. The oxidizing film completely different from the conventional anode. A ceramic-Like material for manufacturing a music instrument is selected from light metal and light metal alloy. A ceramic-like oxidizing film is coated on a surface of the metal or metal array. |
