Carbidizing of Spherical Powders of Niobium, Molybdenum, and Tungsten,
Abstract
The deals with the carbidizing (in lamp-black) of such refractory metals as Nb, Mo and W, obtained in powder form by means of plasma-jet atomizing. The following powder fractions were used: 1200, 800, 700, 500, 400, 300, 250, 200 and 100 mu m. Diffusion annealing was carried out at 1973K for Nb, 1673 and 1773K for Mo and 1873K and 1973K for W, and the time of the diffusion plating of each of the above spherical particle fractions in relation to the above temperatures, required to obtain a carbide coating of specified depth, was calculated with the aid of a Minsk-12 computer.
