Physico-Techological institure of Metals and Alloys of the NAS of Ukraine (Kyiv, Ukraine) UDK 669.2/.8:669.55:620.193 Literary analysis of corrosion properties of tread alloys based on zinc and aluminum is performed. The influence of some chemical elements on the properties of treads with high aluminum content is analyzed. The method of obtaining alloy samples for corrosion research has been improved. Corrosion tests of steel and steel together with aluminumbased treads containing calcium and iron in model seawater were carried out. The samples were in contact with aggressive environments for 240 hours. It has been established that steel without treads corrodes an order of magnitude more than steel that is not protected by treads. Corrosion of steel with tread does not depend on whether the tread is used with the addition of iron or calcium: the data for these two cases coincide within the experimental errors. But calcium protectors themselves lose weight faster than iron protectors. Thus, it is shown that calcium hyperactivates the tread alloy and reduces its capacity and efficiency.
