Abstract

In [1] the structure, properties and operational characteristics of pseudo alloys (Cu-Zr-Y-Nb) -Mo (MДК), which are widely used for the manufacture of electrical contacts and electrodes, were studied in detail. MДК materials [2-5] have a relatively low corrosion resistance, so the task of increasing the corrosion resistance of these materials is urgent. The authors [6] proposed a composite material consisting of a metal matrix - low-alloy copper-based alloy with the following content of components, % wt.: yttrium-0,01-1,0; zirconium 0.01-1.0; niobium-0.01-0.5; the rest is copper, which is strengthened by dispersed particles of molybdenum, copper oxide and molybdenum oxide. The ratio of components in the specified composite material was,% wt .: molybdenum-1,5-15; copper oxide-0.1-5; molybdenum oxide-0.1-5; alloy Cu-Zr-Y-Nb residue.
