In article stages of development of electroerosive processing a floor-matеrials, about an outstanding role of the founder of this method of B.R. Lazarenko, and also a considerable role of its friend and the col- league in researches of the alloyed layers and creation of electrode materials of G.V. Samsonov, results of researches in this area of other known scientists are described. On the basis of scientific and experimental researches a number of conclusions and generalisations which have formed a basis of creation of a new sci- entific direction − electrode materials technology for creation by electroerosive processing of the alloyed layers with the improved operational properties has been formulated.
