• 論文の詳細を見る

• Clad layers of Ni-based alloy were deposited on the power plant machinery parts made of SUS316LN stainless steel by CO_2 laser cladding and plasma cladding. A smooth clad bead was obtained by CO_2 laser cladding. The phases of the clad layers were investigated by laser microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, electron probe microanalysis (EPMA), and energy-dispersive spectroscopy (EDS). The microstructures of clad layers belonged to a hypereutectic structure. Primary phases consisted of boride CrB and carbide Cr_7C_3. The eutectic structure consisted of Ni+CrB or Ni+Cr_7C_3. Compared with plasma cladding, excellent wear resistance, fine microstructures, low dilutions and high Vickers hardness were obtained by CO_2 laser cladding. All these results show that laser cladding realizes higher efficiency and good cladding quality.
