METHOD OF APPLYING COPPER COATING ON TITANIUM HYDRIDE PARTICLES Russian patent published in 2012 - IPC B22F1/02 C23C18/38 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy and may be used to increase thermal stability of titanium hydride powder. Proposed method consists in making diffusion barrier coating on surface of titanium hydride powder particles applied from solution that contains, in g/l: copper sulphate 15-35, sodium-potassium tartrate 60-170, sodium hydroxide 15-50, sodium carbonate 3-35, formalin 6-16, sodium thiosuplhate 0.003-0.001, nickel chloride 2-3. Titanium hydride powder is filled with fresh solution, mixed by magnetic mixer, filtered, rinsed and dried.

EFFECT: 60%-increase in thermal decomposition temperature, reduced hydrogen release rate.
