Formation of Protective Coating on Amorphous Metallic Surfaces by Controlled Adsorption of Functional Oligoperoxides from Aqueous Solutions

Formation of nanostructured functional coatings from water solutions of carbon-chain oligoperoxide surfactants (OPS) composed of vinyl acetate (VA), 2-tert-butylperoxy- 2-methyl-5-hexen-3-yne (VEP), maleic anhydride (MA) and oligoperoxide metal complexes of (OMC) with different contents of coordinated Cu2+ and Fe3+ cations on the Fe78.5Ni1.0Mo0.5Si6.0B14.0 and Fe73.1Cu1.0Nb3.0Si15.5B7.4 amorphous alloys (AMA) has been studied. The existence of several stages of the coating formation depending on oligoperoxide nature and the solution concentration has been established. The nature and concentration of oligoperoxides define the structure and packing density of oligomer molecules in the adsorption layers. The oligomer films coordinated by Cu2+ on the Fe78.5Ni1.0Mo0.5Si6.0B14.0 and Fe73.1Cu1.0Nb3.0Si15.5B7.4 AMA are more rigid.
