[求助] 9.4节~~谢谢

9.4 In order to more fully characterize the crevice-corrosion resistance of iron-base and nickel-base stainless alloys, it is recommended that more than one set of geometric conditions be considered. For example, deeper or tighter crevices, or both, may be required for initiation of crevice corrosion in environments containing chloride concentrations below that typical of seawater.
9.4.1 Effects of crevice tightness can be assessed by evaluating materials over a range of crevice assembly torque levels. The physical properties of the crevice former and fastener may limit the range of study.

9.4 为了更好地表征铁基和镍基不锈合金的抗隙间腐蚀能力,推荐应考虑多套几何学情况。例如,较深缝隙或较致密缝隙,或既深又致密缝隙,都需要在包含氯化物浓度低于一般海水中浓度的环境下进行隙间腐蚀的发生试验。
9.4.1 通过对材料进行一系列缝隙的组合扭矩水平测试,可以评估缝隙致密度的影响。缝隙成形和接合的物理特性可能会限制这一系列研究。
