摘要：Provided is a black coupling member for vehicles, comprising a trivalentchromium black chemical conversion film and a black coating film upon the trivalentchromium black chemical conversion film, on the surface of a zinc-plated metal substrate.The trivalent chromium black chemical conversion film is formed using a hexavalentchromium-free trivalent chromium black chemical conversion treatment solution having aZn ion concentration of no more than 20 g/L. The lightness (L) of the trivalent chromiumblack chemical conversion film is no more than 33. The black coating film includes a blackchemical conversion component, a modified organopolysiloxane, and a friction
coefficient-adjustment component. The black chemical conversion component content is2-25 wt % relative to 100 wt % of the black coating film. The lightness (L) is no more than28.
