摘要：

Anodic behavior of the VK-6 alloy in phosphoric acid solutions was studied potentiometrically, voltammetrically, and by X-ray phase and metallographic analyses. The potential range was determined in which the phase of cobalt-tungsten alloy dissolves with formation of soluble compounds of the above metals and the tungsten carbide phase does not dissolve. The results obtained can be used in reprocessing of hard alloy scrap.
