Producing NiCrAl Alloy by the SHS Method for Use in Thermal Spray Powder Manufacturing
Bora Derin,Umut Demircan,Onuralp Yücel 대한금속·재료학회 2009 METALS AND MATERIALS International Vol.15 No.2
A series of Ni alloys containing 36.15 - 44.54 wt.% Cr and 2.0 - 13.50 wt.% Al was synthesized by Self- Propagating High-Temperature Synthesis (SHS) using a mixture of NiO, Cr2O3 and Al powders in order to obtain low-cost starting materials for thermal spray powder production. The experiments were carried out with the addition of an excess stoichiometric amount of Al between 0 % and 30 %. Additions of CaO and CaF2 were also done to remove sulfur from the alloy and to investigate the effect on metal recovery. Thermochemical simulations of the SHS processes were examined with the FactSage program. The products were characterized by chemical analysis, X-ray diffraction (XRD), electron probe microanalysis (EPMA) and microhardness techniques.
