结论1.研究了铬酸盐溶液在镁合金表面形成的表面层的组成; 2.铬酸盐与镁合金表面的相互作用导致铬酸盐在镁合金表面的强烈吸附，并使铬还原为+3价氧化态; 3.铬酸盐在水中初步氧化的镁合金表面的吸附较弱，其在表面上的量很小，并且其氧化态等于+6.4。已经假定保护层由镁和铬的混合氧化物组成。
Conclusions1.The composition of the surface layers formed when chromate solutions are applied to a magnesium alloy has been studied.2.The interaction results in the strong adsorption of the chromate with the reduction of chromium to the +3 oxidation state.3.Chromate is weakly adsorbed on the surface of a magnesium alloy preliminarily oxidized in water, its amount on the surface is small, and its oxidation state is equal to +6.4.It has been postulated that the protective layer consists of a mixed oxide of magnesium and chromium.
