摘要

氢含量检测是反映铝及铝合金熔体除气效果及其质量是否合格的重要工艺

对获得合格铸件具有十分重要的意义。从铝熔体测氢原理（Sievert定律）出发

对当今比较流行的几种铝熔体定量测氢方法（惰性气体法、电化学法及吸气测压法）及开发的相应测氢仪进行介绍、评价和对比

并指出进一步提高检测速度、降低设备及测试成本将是未来铝液测氢技术的发展方向。

Abstract

The measurement of hydrogen content in aluminum and aluminum alloy melt is an important process to reflect the degassing effect and to ensure the quality of the melt

and it is significant to improve the casting’s quality.The instruments and features of several popular measurement techniques

such as Telegas method

electrochemical method

pressure evaluation method based on Sievert’s law were analyzed

evaluated and compared.It is indicated that those measurement techniques improving high testing speed and decreasing instrument and testing cost will be the future direction of development.
