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 為了更好地表征鐵基和鎳基不銹合金的抗隙間腐蝕能力,推薦應(yīng)考慮多套幾何學(xué)情況。例如,較深縫隙或較致密縫隙,或既深又致密縫隙,都需要在包含氯化物濃度低于一般海水中濃度的環(huán)境下進(jìn)行隙間腐蝕的發(fā)生試驗(yàn)。 9.4.1 通過(guò)對(duì)材料進(jìn)行一系列縫隙的組合扭矩水平測(cè)試,可以評(píng)估縫隙致密度的影響?p隙成形和接合的物理特性可能會(huì)限制這一系列研究。 |
