The expansion coefficient of the said alloy has been improved from 5.6×10 -6 /K to 8×10 -6 /K on the prerequisite of ensuring good properties of tungsten alloys by controlling the alloy component,optimum technical conditions.
Tests of charpy impact of different impact ratio of 93W-Ni-Fe liquid-phase sintering alloy-tungsten at different technological state show the macroscopic law that impact rate from 5 to 40m/s is increased as impact toughness of alloytungsten rises. Addionally, analysis of the impact fracture by SEM has more knowledge to micro-machinism of alloy-tungsten fracture in high rate impact.
Electroplating kinetics of a nickel-tungsten alloy
Electroplating a nickel-tungsten alloy under various electrolysis conditions (direct and alternating current) is studied.
Electrochemical behavior of cobalt in a tungstate melt, as well as the effect of electrolysis conditions on the composition and structure of cobalt-molybdenum (tungsten) alloy deposits from tungstate-molybdate melts is studied.
The potential range was determined in which the phase of cobalt-tungsten alloy dissolves with formation of soluble compounds of the above metals and the tungsten carbide phase does not dissolve.
