This paper deals with K/Na-containing additives in the coatings or cores of electrodes, transforming the martensitic matrix of Fe-Cr-C hardfacing alloy into an austenitic one. The austenitic matrix hardened by the fine dispersed (Cr, Fe){sub 7}C{sub 3}, together with the isolated lumpish eutectic carbide, enhance both the impact and abrasion resistance of this alloy. The authors also found that Na doubled the effectiveness of the additive, and 50% less is needed to get better results compared to the K addition.
