本文用电化学氢渗透技术、定载荷硫化物应力开裂试验等手段,研究了不同回火温度对2Crl3不锈钢中的氢扩散系数、氢溶解度、硫化物应力开裂试验的至断裂时间t_f等的影响。 结果指出,2Crl3不锈钢的硫化物应力开裂试验的至断裂时间随回火温度而变化的规律,与氢在钢中的扩散系数及溶解度随回火温度而变化的规律有一定的对应性。据此,作者认为电化学氢渗透技术有可能作为研究和评定钢的氢脆敏感性的一种有用的手段。
The effect of different tempering temperatures on diffusion coefficient of hydrogen, hydrogen solubility and time to failure in sulfide stress cracking (SSC) test of 2Cr13 stainless steel was studied by means of electrochemical hydrogen permeation technique and constant load SSC test etc. Experimental results show that as the tempering temperature changes, the variation of t_f corresponds well to the variation of the diffusion coefficient and solubility of hydrogen in the steel.Accordingly, the authors hold that the electrochemical hydrogen permeation technique may be used as a useful means in studying the susceptibility of steel to hydrogen embrittlement.
