| titleOfInvention | Method of forming black, non-reflective cladding layer on light metal alloy surface |
| abstract | This invention discloses one kind of microelectronic arc plasma oxidation (MAPO) method which can be used to form a black, non-reflective, durable, thermally stable, homogeneous oxide cladding layer on the surface of the light metal alloy. The thickness of the cladding layer is about 5-70 micrometer which mainly uses an electrolyte based on silicate with addition of an alkali metal hydroxide and alkali metal vanadate (potassium hypovanadate). This invention uses impulse direct current as the power supply to be operated at room temperature (20-30 DEG C). In situation of fixed voltage or fixed current, the current density is 1-10 A/dm<2> and the voltage is 300-500 volts. The impulse time is 0.1-2.0 ms. The impulse interval time is 0.4-16 ms. The ratio of the impulse time and the impulse interval time is 1:4 to 1:8. |
