Research Of Q235Steel Surfactant Argon Arc Cladding Technology

This article reseaches the layer to add different B₄C on Q235Steel by A-TIG andexplores adding the surface active agent or not to test the surface morphology of the layer,organizational structure, and mechanics performance indicators. Determine the weldingparameters of the activity of the argon arc cladding technology by orthogonal experiment method.Test the hardness of the layer by brinell hardness meter, analysis the structurec of layer byoptical microscope and scanning electron microscopy, test wear resistance properties of thecladding layer by wear tester, and test and analysis corrosion resistance of the layer as well asresistance to erosion by different way。The orthogonal test research results show that the optimal parameters by the A-TIG: theprocess parameters are the argon flow6L/min, current strength145A, welding speed120mm/min; wear tests showed that the active argon arc melting layers’s wear resistanceimprove more than doubled to compared with the not adding the active agent; corrosionresistance of studies have shown that the addition of active agent cladding layer corrosionresistant static acid increased by2to4times the comparable matrix; erosion experiments show:join the active agent resistant oil medium quartz sand erosion performance of the cladding layerincreased by2to4times higher than the matrix. In summary, the organization and morphologyof the cladding layer is changed by adding the active agent, and its overall performance hasimproved.
