ZINC MODIFIER POWDER Russian patent published in 2001 - IPC

Abstract RU 2170643 C1

FIELD: thermochemical treatment of metal articles, particularly, process of thermodiffusion galvanizing in powder media. SUBSTANCE: zinc modified powder with zinc content up to 99 wt.% has surface film from particles of zinc oxide of fine-grained structure. In this case, zinc powder particles have sizes from 4 mcm to 1 mm, and sizes of particles of active zinc oxide in surface film is ranging from 0.03 to 0.5 mcm. EFFECT: improved technological effectiveness of process of use of powder in economical and ecological aspects and guaranteed high technological properties of coatings. 1 tbl, 8 ex
