摘要
The invention discloses an iron-based amorphous nanocrystalline laser cladding composite coating and preparation and test methods thereof; the composition of the cladding composite coating meets the molecular formula: FeaCobNicBdSiyNbe, wherein a, b, c, d, y, and e respectively represent the atomic percentage of the corresponding alloy element; a plus b plus c plus d plus y plus e equals 100; the preparation method is: weighing the raw materials and mixing to obtain the alloy powder, substrate pretreatment, tiling the alloy powder on the surface of the substrate, the laser beam is scanned vertically to perform laser cladding on the alloy powder. The composite has a certain amorphous content, high microhardness, excellent wear resistance, and outstanding fracture strength. The preparation process is simple, the raw materials do not contain rare earths or volatile elements, and the application prospect is broad.
