▎ 摘　　要

NOVELTY - An anti-corrosive metal housing (100) comprises metal substrate (102); passivation layer (110) including an oxyanion selected from molybdate, vanadate, phosphate, chromate, stannate, and/or manganese salt; and sealing layer (120) including sodium silicate, aluminum powder, zinc powder, graphene powder, and/or clay powder. USE - An anti-corrosive metal housing for an electronic device (claimed). ADVANTAGE - The anti-corrosive metal housing has excellent color stability, and is resistant to corrosion and finishes, and provides electronic device with excellent esthetic appearance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) electronic device comprising electronic component of an electronic device and the anti-corrosive metal housing to support the electronic components; and (2) application of anti-corrosion treatment to a metal substrate of a housing for an electronic device, which involves treating a metal substrate in an aqueous oxyanion passivation bath to form a passivated metal substrate, where oxyanion passivation bath includes 3-15 wt.% molybdate, vanadate, phosphate, chromate, stannate, and/or manganese salt, and treating the passivated metal substrate with an aqueous sealing dispersion to form the metal substrate with the anti-corrosion treatment on it, where the sealing dispersion includes 5-30 wt.% sodium silicate, aluminum powder, and/or zinc powder, and 0.1-3 wt.% graphene powder and/or clay powder. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an anti-corrosive metal housing for an electronic device.
