Abstract
The coatings consisting of Fe0.64 Ni0.36 dendrites as matrix and (Fe, Cr)7 (C, B)3 interdendritic compounds as reinforcement were fabricated on the medium steel substrate by laser cladding using the Fe-based powders with different Co content, and Co is uniformly dissolved in the coatings. Compared with the coatings containing 1% and 5% Co, the coating containing 3% Co increases in the area fraction of the interdendritic region by about 5%, in the microhardness nearby the interface by about HV 55 and in the interfacial bond strength by about 30 MPa. The interface fracture morphology exhibits the tear appearance, which can be characterized as the ductile fracture.
