Compressive strength for the BMG(bulk Metallic Glasses) of Ni57Zr20Ti18Si5 were lower than those of BMG rods produced by warm extrusion ,or copper mold casting method. Microstructural examination by optical microcope, SEM and EDS showed that oxidation had occurred during PASintering. In order to prevent the powder from the oxidation during PASintering, Ni coating for Ni57Zr20Ti18Si5 amorphous powder by electroless-plating method was performed. Microstructural examination for Ni coated layers after PASintering indicated that the Ni coating had been so effective to prevent powder from oxidation during PASintering. Sintering behaviors of Ni57Zr20Ti18Si3Sn2 represent the same as those of Ni57Zr20Ti18Si5. 한국재료학회 PAS법을 이용한 Ni기 비정질 분말의 소결 Sintering of Ni-Based Amorphous Alloy Powders by Plasma Activated Sintering Process Article 2 한국재료학회지, v.15, no.12, pp.765 - 772 한국재료학회지 15 12 765 772 kci ART000978850 PAS(Plasma Activated Sintering) Ni based amorphous alloy Electroless-plating PAS(Plasma Activated Sintering) Ni based amorphous alloy Electroless-plating
