Abstract
Purpose: The aim of this study was to analysis the composition on the centrifugal casting and the oxide on the casting temperature.
Methods: The nickel based alloy were used in this study. Wax pattern specimens (10*10*2) were invested with phosphate-bonded investment in metal rings, the liquid/powder ratio and overall burn-out schedules for these investments were followed in accordance with the manufacturer’s instructions. After casting, the alloy specimens were evaluated as regards composition(EPMA). The casting temperatures were as follows: 1400℃ and 1700℃. The quantitative analysis of oxides were scanning electron microscope(SEM), energy dispersive spectroscopy(EDS) and line scanning.
Results: Nearer the injection lines showed that there is a large amount of nickel. Quantitative of oxides of Ni-Cr alloy cast from 1400℃ is lager than Ni-Cr alloy cast from 1700℃
Conclusion: Casting when using a centrifugal casting machine centrifugal force affects the composition of the alloy. The higher the temperature, the amount of oxide that is generated many.
