| Abstract: | Different amount of nanometer CeO2 powder was added into the alkaline coating of iron powder electrode. The microstructure and mechanical properties were analysed and measured. The effects of nanometer CeO2 powder on the microstructure and properties of welded joint were studied. The experiment results indicated that the addition of appropriate amount of nanometer rare CeO2 powder into the coating of electrode could refine microstructure,increase ratio of acicular ferrite in the microstructure, and enhance ... |
