Influence of Surfacing Current on Microstructure and Wear Resistance of Fe60 Alloy Surfacing Coating

Article Preview

Abstract:

Fe60 alloy surface coating was prepared on Q345 by plasma surfacing. The hardness and wear resistance of surfacing coating were tested by Rockwell Hardness Tester and dynamic load abrasive abrasion Tester. The microstructure of surfacing coating was studied by Optical Microscopy. The Influence of the surfacing current on hardness, microstructure and wear resistance were investigated.The results showed that, the samples prepared by 140 A exhibited excellent wear resistance, meanwhile many equiaxed grains were observed to distribute uniformly in the samples.
