The development of modern technology requires a constant increase in reliability and durability products. Widely used the practice domestic foreign engineering coatings from electrolytic chromium for several hundred hours are triggered, they unsatisfactorily working on friction wear at high temperatures. subject study were powder materials based nickel PG-SR3 PG-SR4. work is devoted to formatio...

The alloying of Nb₅Si₃ modifies its properties. Actual compositions of (Nb,TM)₅X₃ silicides in developmental alloys, where X = Al + B + Ge + Si + Sn and TM is a transition and/or refractory metal, were used to calculate the composition weighted differences in electronegativity (Δχ) and an average valence electron concentration (VEC) and the solubility range of X to study the alloying and proper...
