Study on Microstructure and Wear Resistance of Flame Spray Welding Ni-based Coatings AITranslate
Abstract AITranslate
Using Ni60A,Ni60CuMo and Ni60WC10 powders of 53 - 150 μm particle size as raw materials, the corresponding coatings were prepared with Castolin SuperJet S flame spray welding system. The mi- crostructure and wear resistance of the coatings were analyzed by metallographic microscope,X-ray diffrac- tometer （XRD）, scanning electron microscope （SEM） and friction and wear test machine. The results show that all the Ni60A,Ni60CuMo and Ni60WC10 coatings exhibit high hardness （HRC^57.0） and lower po- rosity （〈1.0%） ,and there is metallurgical bond between the coating and the substrate. The main diffrac- tion peaks of each coating are from Ni-based solid solution,and there is obvious WC diffraction peaks in the Ni60WC10 layer. The wear resistance of Ni60WC10 coating is about 2.5 times higher than that of Ni60A coating and about 3.5 times higher than that of Ni60CuMo coating.
