| titleOfInvention | Surface treatment method for hot-dip galvanized steel by micro-electric-arc plasma oxidation |
| abstract | This invention relates to a method of forming an aluminum oxide and zinc oxide plating layer on the surface of hot-dip galvanized steel by utilizing the micro-electric-arc plasma discharging deposition/oxidation. As disclosed is mainly the formation of a plating layer on the substrate of hot-dip galvanized steel which comprises aluminum oxide and zinc oxide, and the method to improve the anti-corrosion properties of the hot-dip galvanized steel. In a reactor tank, a stainless steel piece is connected to the cathode of a pulse power supply while the article to be treated is connected to the anode of the pulse power supply. This method utilizes a pulse power supply which supplies at fixed voltage and current and utilizes an electrolyte which contains 10-30 g/L of sodium aluminate and 2-20 g/L potassium hydroxide or sodium hydroxide with the addition of 5-30 g/L sodium phosphate. The pulse time and the interval time between two pulses are the same and in the range of 0.1-5.0 ms. The current density is 5-20 A/dm<2> with a peak voltage at 300-450 V for 10-60 minutes of treatment time. In addition, the article to be treated can be pre-electroplated with a polymer film. The film thickness of the plating layer by this invented method is around 10-100 mum. |
