Influence of the cooling method on structure formation of pb-0.1%ca-0.3%sn battery alloy

Modern development of automotive and railway transport as well as autonomous power supply systems is accompanied by increase of demand and requirements for power sources. Having some number of advantages, nowadays lead-acid batteries are occupying a significant partition of secondary power systems market, and their improvement mainly occurs as a result of polishing of batteries' specific characteristics and materials consumption reducing. At the same time some special attention is given to operating characteristics and properties of current collectors, as to an important component whose quality largely determines the durability of batteries. In present work the investigations of physicochemical properties and structure of Pb-0.1%Ca-0.3%Sn alloy specimens been conducted. The samples were obtained in three different ways ? by using of two industrial methods (casting and rolling) as well as an experimental method which is based on quenching from a liquid state. The investigations results showed some significant differences in structure and properties of quenched strips and its give a possibility to urge the necessity of further researches of tempered strips during exploitation.
