Abstract

Tests for assessing prestressing steels' susceptibility to hydrogen-induced stress corrosion cracking are essential for approvals, in-house monitoring, and third-party material testing. According to ISO 15630-3, the time to brittle fracture by constant load under corrosive conditions in thiocyanate test solutions (A or B) at 50°C is measured. In the literature, a high scattering in stress corrosion tests is reported, which questions the integrity of the test procedure. This paper shows the results of studies about the influence of solution composition on hydrogen charging in electrochemical and permeation measurements. Electrochemical experiments show that polished steel surfaces without common drawing layers have more consistent free corrosion currents, polarization resistances, and B-values in solution A with low scattering compared to the solution B experiments. The influence of temperature at 50°C and an ambient temperature of 22°C was also tested.

预应力钢材的应力腐蚀试验--第 1 部分:表面条件和试验溶液成分对充氢的影响
评估预应力钢材对氢诱导应力腐蚀开裂敏感性的测试对于审批、内部监控和第三方材料测试至关重要。根据 ISO 15630-3,在 50°C 的硫氰酸盐测试溶液(A 或 B)中,在腐蚀条件下通过恒定载荷测量脆性断裂的时间。据文献报道,应力腐蚀试验中的散射率很高,这对试验程序的完整性提出了质疑。本文展示了在电化学和渗透测量中溶液成分对氢充电影响的研究结果。电化学实验表明,与 B 溶液实验相比,没有普通拉丝层的抛光钢表面在散射较低的 A 溶液中具有更一致的自由腐蚀电流、极化电阻和 B 值。此外,还测试了温度在 50°C 和环境温度 22°C 时的影响。
