Certain inclusions in high-strength 60Si2Mn-Cr spring steel result in poor resistance to localized corrosion. In this work, to study the effect of inclusions on the localized corrosion behavior of spring steel, accelerated corrosion tests were performed by immersing spring steel in 3wt% FeCl3 solution for different times. The results show that severe corrosion occurred in areas of clustered CaS inclusions. Sulfide inclusions containing Ca and Mg induced the strongest localized corrosion susceptibility. For the case of (Ca,Mn,Mg)S inclusions, the ability to induce localized corrosion susceptibility is ranked as follows: MgS > CaS > MnS. Moreover, CaS, (Ca,Mn)S, and (Ca,Mn,Mg)S inclusions were mainly responsible for inducing environmental embrittlement.

非金属夹杂物对弹簧钢局部腐蚀的影响

高强度60Si2Mn-Cr弹簧钢中的某些夹杂物导致对局部腐蚀的抵抗力较差。在这项工作中,为了研究夹杂物对弹簧钢局部腐蚀行为的影响,通过将弹簧钢浸入3wt%FeCl 3溶液中不同时间来进行加速腐蚀试验。结果表明,在聚集的CaS夹杂物区域发生了严重的腐蚀。含有Ca和Mg的硫化物夹杂物引起最强的局部腐蚀敏感性。对于(Ca,Mn,Mg)S夹杂物,其诱导局部腐蚀敏感性的能力等级如下:MgS> CaS> MnS。此外,CaS,(Ca,Mn)S和(Ca,Mn,Mg)S夹杂物是引起环境脆化的主要原因。
