COMPOSITES FOR CONTACTS AND ELECTRODES

The research done on composites of the type of W(Mo)- and Ag(Cu)-based pseudoalloys for electric switchgear contacts (make and break contact s) is reviewed. The ideas of I. N. Frantsevich on composites for elect rical uses are shown to have had a great influence on the development of this field in materials sciences and on the work of his pupils and followers. The distinctive features of composites and parts made to sa tisfy specific requirements for increased adhesiveness and service lif e and lower consumption of expensive materials are described.
