FIELD: metallurgy.
SUBSTANCE: method involves heating and exposure of rotated container pre-loaded with steel items and saturating mixture. The latter contains titanium dioxide in quantity of 1-3 wt % with grain size of up to 1 mcm, monosubstituted calcium orthophosphate in quantity of 2-6 wt % with grain size of 74-150 mcm, zinc powder with grain size of 25-630 mcm in quantity of 60-90 wt %, which is obtained by method of water spraying and inert material. Thermodiffusion zinc coating is performed in non-tightly closed container.
EFFECT: improving coating quality, reducing power consumption and increasing the efficiency of thermodiffusion zinc coating process.
