| 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:argon-blowing time 6 s,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. |
