چکیده انگلیسی
The interface region of welded A508-Alloy 52Â M is characterized by scanning probe microscope (SPM) techniques, scanning electron microscopy (SEM)/energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM)/Energy Dispersive Spectroscopy (EDS) and scanning vibrate electrode technique (SVET). The regions along the welded A508-Alloy 52Â M interface can be categorized into two types according to their different microstructures. In the type-I interface region, A508 and Alloy 52Â M are separated by the fusion boundary, while in the type-II interface region, A508 and Alloy 52Â M are separated by a martensite zone. A508, martensite zone and grain boundaries in Alloy 52Â M are ferromagnetic while the Alloy 52Â M matrix is paramagnetic. The Volta potentials measured by scanning Kelvin probe force microscopy (SKPFM) of A508, martensite zone and Alloy 52Â M follow the order: V52Â MÂ >Â VA508Â >Â Vmartensite. The corrosion behavior of A508-Alloy 52Â M interface region is galvanic corrosion, in which Alloy 52Â M is cathode while A508 is anode. The martensite dissolves faster than Alloy 52Â M, but slower than A508 in the test solution.
