Abstract

This paper presents results of research of multilayer carbon diffusion protective aluminium-silicon coatings. Aluminium-silicon coatings created on high-temperature creep resist cast iron GX30NiCrSi30-18 were manufactured by immersion in active mixture containing aluminium and silicon powders, flux and binder. The samples prepared in this way were annealed at temperature about 900 °C. The samples differed in surface conditions (machined and as-cast conditions). The structure of these coatings is compact and triple zonal.
