Essay

The dissertation is devoted to the problem of phase composition formation in molibdenum and tangsten electrodeposited alloys as well as to the comparision of data cjncerning the structure of alloys obtaned by means of electrocrystallisation and throught high-rate quenching of melt. The thesis developes the trend of prognosticating the alloys structure and properties as a result of the analysis of non-equilibrium cristallizatoin general regularities. Methods comprising deposition of amorphous tungsten alloys with ferrometalls and deposition of durable molibdenum and tungsten coatings with chrome have been developed. The basic finding have been currently applied in pipe-rolling processes insuring increase in the lifetime of the rolling tools.
