Certain characteristics of zirconium-containing anodic films on aluminum

Some data on zirconium-containing layers plasma-electrochemically (P-E) applied to A7 aluminum alloy (obtained by using x-ray spectral and diffraction analyses, electron microscopy, as well as measuring their thickness and visible light reflection) are discussed. The properties of the P-E applied structures formed under power-drop conditions are studied as functions of the potassium hexafluorozirconate bath temperature (20–70°C) and initial voltage (300–500 V).
