Abstract
This paper presents the factors which are important to consider in evaluating a given metal-electrolyte system for the application of anodic protection. The general requirements are discussed first, and then a number of examples are given. The anodic protection process is applicable to highly conductive solutions which exhibit the property of establishing a passive range with the metal in question. In general, the oxy acids, the bases and the salts are applicable. The greatest class exclusion are those solutions containing the halogens. The effects of temperature, type of alloy and economic aspects of the system are discussed. Data is presented to show that used with the 18/8 stainless steels the anodic protection process could be applied to HNO3, H3PO4, NaOH. Al3(SO4)2 and NH4 NO3 solutions. 5.9.4Keywords
