| Abstract: |
| The contents of chemical elements and their changes affect the properties of nickel-based alloy materials. Therefore, the accurate detection and strict control of the chemical composition of nickel-based alloys are of great significance to improve and guarantee the properties of nickel-based alloys. By optimizing the parameters of the instrument and using sample control method, a method for determining the contents of Al, C, Cr, Co, Cu, Fe, Nb, P, Si, S, W and Mo elements in nickel base alloy by spark discharge atomic emission spectrometry was established. The optimized test conditions are as follows: (1) argon-blowing time: 6 s; (2) pre-combustion time: 6 s; The integral time: 8 s. Three kinds of conventional nickel base alloy samples were analyzed by this method. The measured values are consistent with the results of the current national standard analytical methods. |
