吸氢是导致零件在加工或使用时产生氢脆或氢裂的根源。钢在冶炼时、热加工时、表面处理时以及在氢气气氛中或其它含氢介质中使用时都会造成吸氢。氢脆或氢裂的敏感性是随着钢的强度增加而加大的。30CrMnSiNi2A钢使用的强度范围在140～180公斤·力/毫米~2,是一种常用的超高强度钢。按现行工艺方法,用30CrMnSiNi2A钢制成的零件中含氢量通常高于原材料中的含氢量,而热处理和表面处理工序是造成吸氢的重要环节。分析造成吸氢的工艺条件及吸氢后对性能的影响。有助于对吸氢机制和脱氢(除氢)方法的研究,并可寻求降低零件含氢量的方法,避免因热处理或表面处理工艺过程不正确
Hydrogen absorption is the source of hydrogen embrittlement or hydrogen cracking that can cause parts to be processed or used. Steel absorbs hydrogen during smelting, hot working, surface treatment, and when used in a hydrogen atmosphere or in other hydrogen-containing media. The sensitivity of hydrogen embrittlement or hydrogen cracking increases with increasing strength of the steel. 30CrMnSiNi2A steel strength range of 140 to 180 kg · force / mm ~ 2, is a commonly used ultra-high strength steel. According to the current process method, the content of hydrogen in the parts made of 30CrMnSiNi2A steel is usually higher than the hydrogen content in the raw materials, and the heat treatment and the surface treatment processes are the important links for hydrogen absorption. Analysis of the resulting hydrogen absorption process conditions and the impact of hydrogen on the performance. Helps to study hydrogen absorption mechanisms and dehydrogenation (hydrogen removal) methods and seeks ways to reduce the hydrogen content of parts to avoid incorrect heat treatment or surface treatment processes
