用ITHAC—11型快速测氢仪对30CrMnSiA钢按螺栓生产工艺流程在实验室条件下测得原始态、热处理后、酸洗、电镀后的氢含量,测得镀锌件和镀镉件以不同规程去氢退火处理后之氢含量。实验结果表明,镀锌镀镉是钢件吸氢的主要环节,改变电镀工艺可有效地减少吸氢量,适当选择去氢退火规程才能确保较低的含氢量。 With ITHAC-11 rapid hydrogen meter for 30CrMnSiA steel bolt production process measured in the laboratory under the conditions of the original state, after heat treatment, pickling, hydrogen content after plating, measured galvanized and cadmium plated parts are different Hydrogen content after dehydrogenation anneal. The experimental results show that galvanized cadmium plating is the main part of hydrogen absorption of steel. Changing the electroplating process can effectively reduce the amount of hydrogen absorption, and proper dehydrogenation annealing procedure can ensure a lower hydrogen content.
