【Abstract】 Some characteristics of glow discharge for analysis of copper alloy were studied. The influences of GD source structure, operating parameters (gas pressure, discharge potential) and the size of sample on emission spectra, sputtering rate and electric behavior were investigated. The discharge stability was also examined. Under the selected operation conditions, Al and Mn in copper alloy were determined and a satisfactory result was achieved.更多还原
