Abstract

In this work, the determination of the oxygen and nitrogen content in powders of nickel alloys EP648, VPr50 and VG159 was carried out by reductive melting in a current of an inert carrier gas, followed by detection of oxygen in an infrared cell and nitrogen in a conductometric cell of a Leco TC-600 gas analyzer. During the experiments, various catalysts were used – tin and nickel, necessary for the complete extraction of oxygen and nitrogen from nickel alloy powders. Preparation of a sample for analysis is described.
