MEDIUM FOR COMPLEX SATURATION OF METAL SURFACE Russian patent published in 1999 - IPC

FIELD: chemical and thermal treatment, more particularly media for multicomponent diffusion saturation of metal surface. SUBSTANCE: medium comprises active components and carbon- graphite materials as inert constituent, ratio of components being as follows, vol %: active components, 30-45; and carbon-graphite materials, the balance. Active components comprise boron and aluminium in 1:2 ratio, or silicon and ferrotitanium in 4:1 ratio. EFFECT: increased intensity of complex diffusion saturation of metal surface, improved quality of the surfaces to be treated, higher heat resistance and scale resistance of surfaces to be treated. 2 ex, 6 tbl
