摘　　要：某医用稀配罐在使用过程中出现泄漏现象。采用宏观观察、化学成分分析、能谱分析等方法对该稀配罐泄漏原因进行分析。结果表明:稀配罐内层材料使用不当,使内层材料的抗氯离子应力腐蚀能力变差,在NaCl溶液的作用下,稀配罐内层发生应力腐蚀,且罐体没有经过退火处理以消除焊接热应力,导致焊缝周围形成了裂纹,最终稀配罐发生泄漏事故。A medical dilution tank experienced leakage during use.The causes of the leakage in the dilution tank were analyzed by macroscopic observation,chemical composition analysis,energy spectrum analysis.The results show that improper use of the inner layer material in the dilution tank resulted in a decrease in its resistance to chloride ion stress corrosion.Under the action of NaCl solution,stress corrosion occurred in the inner layer of the dilution tank.The tank body was not annealed to eliminate welding thermal stress,led to the formation of cracks around the weld seam,and ultimately caused leakage accidents in the dilution tank.
