摘要
PURPOSE: A filler tube for an automobile and a surfacing method of a filler tube for an automobile are provided to make a chassis lightweight and to improve productivity by manufacturing a filler tube with aluminum, and to extend the service life of a product by forming an oxide layer having high hardness and excellent corrosion resistance on the surface of a filler tube. ;CONSTITUTION: A surfacing method of a filler tube for an automobile comprises the steps of: rotating at high speed and rubbing with the surface of a filer tube to have specular gloss(S1); removing impurities from the surface of the filler tube, and cleaning with acid to remove an aluminum oxide layer formed naturally on the surface of the filler tube(S2); removing a sulfuric acid solution from the surface of the filler tube(S3); etching with alkali to remove an aluminum oxide layer formed naturally on the surface of the filler tube(S4); removing a sodium hydroxide solution and impurities from the surface of the filler tube(S5); forming an oxide layer on the surface of the filler tube(S6); digesting the filter tube in a nickel fluoride solution(S7); removing the nickel fluoride solution from the surface of the filler tube(S8); and drying the filler tube with hot air(S9).;COPYRIGHT KIPO 2011
