Microstructure and Properties of 6061 Aluminum Alloy Superficially Modified by Electron Beam Alloying with 1Cr13 Stainless Steel

Abstract:

1Cr13 stainless steel was pre-coated on the surface of 6061 aluminum for electron beam alloying, then the microstructure and properties of the modified layer was discussed and analyzed. Using Scanning electron microscopy (SEM), EDAX energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and other analytical testing methods to analyze the microstructure and phase composition of the modified layer; Using the HX-1000TM automatic turret micro-hardness tester and HSR-2M high-speed reciprocating friction and wear tester to respectively measure its hardness and wear, finally to analyze the modification effect. The results showed that: between the alloyed layer and the substrate obtains a good metallurgical bonding; the modified layer organization composes mainly of martensite and Al-Fe compounds, and has fine grain; the hardness of the strengthening layer is about 4 times that of the substrate, and its wear resistance is a quarter of the matrixs.
