Effect of ac Polarization on Characteristics of Coatings formed from Polyphosphate Electrolytes of Ni(II) and Zn(II)

“…However, only anodic polarizations have been commonly employed. A considerable progress has also been made in this area, e.g., conditions have been developed in which layers containing oxides of transition metals [19,20], spinels [21], phosphates [22324], and perovskite structures [25,26] can be obtained on aluminum alloys. These layers have found use or show promise in medicine and catalysis, as active elements of gas analyzers, layers resistant to hard ultraviolet and protecting from the action of corrosive media, and structures exhibiting bioinert or biocide properties.…”

Anodic-spark layers on aluminum and titanium alloys in electrolytes with sodium phosphotungstate

“…Coatings of various compositions and purposes can be obtained in electrolytes of this kind. For example, wear-resistant coatings containing a-Al 2 O 3 are obtained in solutions with hexafluoroaluminate complexes [7]; corrosionresistant coatings with vanadium oxides, in electrolytes with phosphovanadate heteropolyanions [8,9]; biocidal coatings with zinc phosphates, in solutions with zinc polyphosphate complexes [10]; bioinert coatings with hydrooxyapatite for implants, in electrolytes with calcium glycerophosphate complexes [4]; and light-reflecting coatings that contain ZrO 2 and are resistant to the action of hard ultraviolet, in solutions with alkali metal hexafluorozirconate complexes [11].…”
