Abstract

Characteristic of standard sacrificial alloys on the base of aluminum is extremely low content of the cathode impurity elements. Due to this requirement, the stable electrochemical parameters and high efficiency of aluminum anodes is not always achieved.Falling characteristics of tread material can be attributed to their passivation - reduction of oxidation of the material of the tread due to the formation of a thick oxide layer on the surface of аnodic protector.This paper presents data as to how to stabilize the electrochemical properties of sacrificial zinc anodic materials that contain aluminum, zinc. Are discussed the principles of alloying that help to reduce passivation of the tread material.

Keywords: sacrificial aluminum alloys, alloying of calcium, electrochemical characteristics
