Abstract

Fe-Cr-C and Fe-Cr-C-Ti coatings were prepared by reactive plasma cladding in this paper. The crack morphology and fracture surface of the Fe-Cr-C coating were observed by SEM. The effect of titanium addition on the crack of Fe-Cr-C coating was analyzed. The results show that the coating cracks mainly consist of crack perpendicular to the fusion line, defect-induced crack and intergranular crack. The crack rate of Fe-Cr-C-Ti coating was obviously decreased after Titanium was added. When the titanium content is below 8 wt.%, with the increase of titanium content, the crack rate of Fe-Cr-C-Ti coating decreases obviously. When titanium content is between 8wt.% and 13wt.%, there are no cracks in the Fe-Cr-C-Ti coating. When the titanium content exceeds 13 wt.%, with the increase of titanium content, a small number of cracks begin to appear. The addition of titanium increases the toughness of the Fe-Cr-C-Ti coating and reduces the stress concentration.
