Effects of shape and distribution of the hard phases (Fe, Cr)7C3 and Cr7C3 on wear resistance of Fe5 deposited metal obtained by plasma arc welding with electromagnetic stirring were investigated. The deposited layers were subsequently characterized by SEM observation, wear tests and hardness measurements. The hardness of the deposited layers was increased and then decreased with increasing the applied current. With the current of 3 A and the electromagnetic frequency of 10 Hz, the hardness of deposited metal reached maximum value of about HRC 68, which was increased about 19% compared with that of the deposited metal without electromagnetic stirring. The wear weight loss of the deposited metal with 3 A and 10 Hz is greatly decreased. It is confirmed that the shape and the distribution of hard phase significantly affect wear resistance of the deposited metal. The slag M7C3 is transformed into hexagon during electromagnetic stirring with 3 A and 10 Hz. And the regular distribution of hexagon M7C3 in the deposited metal resulted in the excellent wear resistance.
