Peculiarities of Modification of Amorphous Alloys Surface with Oligomer Coatings from Alcohol Solutions
摘要
The modification of the contact and external surfaces of strip amorphous alloys Fe78.5Ni1.0Mo0.5Si6.0B14.0 and Fe73.1Cu1.0Nb3.0Si15.5B7.4 with 1% solutions of oligoperoxides based on vinyl acetate, 2-tert-butylperoxy-2-methyl-5-hexen-3-ine (VEP), maleic anhydride and n-vinyl pyrrolidone, VEP, and 2-phosphonooxy ethyl 2-methacrylate in isopropyl alcohol were investigated by the methods of voltammetry, impedance spectroscopy, scanning electron, and atomic force microscopy. The formation of denser coatings on the surface of the Fe78.5Ni1.0Mo0.5Si6.0B14.0 strip and the smoothing of its topography due to the local adsorption of macromolecules of oligoperoxides were established.
