去氢处理

充氢后的堆焊层经630℃×4h去氢处理可消除氢脆现象，使塑韧性恢复。

After dehydrogenation at 630 ℃ for 4 hours , the ductility and toughness of the overlay which was initially charged with hydrogen is recovered and hydrogen embrittlement is eliminated .

结果表明，联合去氢处理具有改善合金组织、提高性能的作用。

It has been shown that the combined process improves structure and tensile property , particularly high temperature property .

研究了连杆圆拉刀的氮碳硫氧共渗与去氢处理工艺，以及渗层组织结构、渗层深度、性能、渗层含氮量与拉刀寿命的关系。

In this paper the sulpho nitro oxy carburizing and the hydrogen removing technology of round broach , the structure of diffusion layer and the relation between the depth , properties , the hydrogen content of diffusion layer and the service life of the broach are studied .
