国防和手表工业用的钨合金材料,其成份为:钨在90%以上,铁、镍为1～5%,钴、铜在0.5%以下,铬1%以下,锰为0.05%左右.本文通过钨合金的ICP光谱测定的研究,对国产GP3.5—E型高频发生器光源的电学性能和被测元素谱线强度之间的影响作了初步探讨.进行了等离子参数和内标元素的选择试验.用样品考察了本方法的精度,并与化学方法进行了对照.实验证明:ICP—AES技术能满是钨合金成份测定的要求.
The composition of the tungsten alloy used in the national defense and the watch industry is as follows: tungsten is more than 90%, iron and nickel are 1-5%, cobalt and copper are less than 0.5%, chromium is less than 1% and manganese is about 0.05% Tungsten alloy ICP spectrometry study of the domestic GP3.5-E-type high-frequency generator light source electrical properties and the measured element line intensity between the impact of a preliminary study carried out plasma parameters and internal standard elements Select the test sample with the accuracy of the method, and compared with the chemical methods.Experiments show that: ICP-AES technology can be full of tungsten alloy composition determination requirements.
