Description
Summary:Using the methods of X-ray phase analysis, scanning electron microscopy, and Auger spectroscopy, the features of the joint precipitation of elemental cobalt and nickel on the surface of titanium of various dispersions from aqueous solutions are studied. It has been established that, in the process of deposition on titanium microparticles, intermetallic compounds are formed, the phase composition of which depends on the prehistory and particle size of the initial titanium powder: the CoNi intermetallic compound is formed mainly on the surface of particles of dispersed titanium of PTM grade, while Co 3 Ni is mainly formed on the surface of particles of dispersed titanium grade PTK-1. It is shown that the specific surface area, total volume, and average pore diameter of the formed Ti–CoNi and Ti–Co 3 Ni systems surpass similar indicators of the initial samples of PTM-1 and PTK-1dispersed titanium.
