Quenching and partitioning (Q&P) treatments result in promising mechanical properties of advanced high-strength steels. However, recent studies indicate that Q&P steels are very susceptible to hydrogen embrittlement (HE). Using slow strain-rate tests, the effects of hydrogen charging in different media without and with recombination poison were investigated for Fe-0.38C-1.92Si-0.66Mn-1.39Cr in quenched and tempered as well as Q&P conditions. In addition, corrosion tests and Zn electroplating of tensile specimens were performed. In both heat-treatment states, it was found that the intensified hydrogen-charging conditions using a recombination poison strongly impact the result of HE investigations: HE only occurs when a recombination poison is present. In addition, the negative influence of hydrogen formed during Zn electroplating can be limited by using proper electrolytes and electrical parameters. This allows keeping the HE susceptibility of the Q&P steel low in practical applications when recombination poisons are absent.

淬火和分配（Q＆P）处理可导致先进的高强度钢具有良好的机械性能。但是，最近的研究表明，Q＆P钢非常容易产生氢脆（HE）。使用慢应变速率测试，研究了在淬火和回火以及Q＆P条件下，Fe-0.38C-1.92Si-0.66Mn-1.39Cr在不同介质中添加和不添加复合毒物的情况下氢充填的影响。此外，还对拉伸试样进行了腐蚀试验和电镀锌。在两种热处理状态下，都发现使用复合毒物的加氢条件强烈影响了HE研究的结果：HE仅在存在复合毒物时才会发生。此外，锌电镀过程中形成的氢的负面影响可以通过使用适当的电解质和电参数来限制。在没有重组毒物的实际应用中，这可以使Q＆P钢的HE敏感性保持较低。
