摘　　要：铝合金复合钎焊材表面自然吸附氧化膜会对铝热交换器钎焊造成不良影响。使用X射线光电子能谱仪(XPS)对比分析了不同条件下的铝材氧化膜厚度和表面镁含量的变化情况,确定了合适的氧化膜检测方法和退火工艺。结果表明,氮气保护并直接出炉冷却的退火工艺,能减少氧化膜厚度并降低生产成本。The natural adsorption of oxide film on the surface of aluminum alloy composite brazing material will have adverse effects on the brazing of aluminum heat exchanger.By using X-ray photoelectron spectroscopy(XPS),the changes of oxide film thickness and surface magnesium content were compared and analyzed under different conditions,and the appropriate oxide film detection method and annealing process were determined.The results show that the annealing process of nitrogen protection and direct cooling after discharge can reduce the thickness of oxide film and reduce production costs.
