Coatings produced in aluminium bath on high-carbon alloys with additions of chromium and nickel

In this study the problem of coatings produced in liquid aluminium on high-carbon Fe-C-Cr and Fe-C-Ni alloys has been discussed. Aluminising has been carried out at temperatures of 710oC and 745oC during the time of 30 to 900 seconds. The morphology of thus produced coatings has been examined along with the chemical composition and phase constitution of individual layers. Microhardness measurements have been taken.
