Effects of Mo, Nb, Ti on mechanical properties and corrosion resistance of 22.5% Cr ferritic stainless steel were investigated. The results show that Mo exists in ferritic stainless steel mainly in the solution treatment condition, and it can enhance steel＇ s strength through solid solution strengthening. In Ti ＋ Nb dual-stabilized ferritic stainless steel, the steel＇s toughness decreases obviously because coarse TiN particles form and some metallic compounds precipitate along the grain boundaries. In Nb single-stablized ferritic stainless steel, Nb exists either in the solution treatment condition or in the form of dispersed precipitates Nb（C, N）, which will act as the nuclei of precipitation of the fine （r phase. As a result, the precipitation of the coarse σ phase along the grain boundary can be inhibited, leading to significant improvement in steel＇ s toughness at a low temperature. Based on these, high corrosion-resistant ferritic stainless steel B445R was developed for the building cladding system. Test results show that B445R has a superior corrosion resistance to austenitic 316 L in chloride solution. Besides, it has a good forming property and weldability. All these make it an ideal decorating material for the building cladding system in severe coastal regions.

皮克林(Pickering)乳液是一种由固体颗粒代替传统乳化剂形成的新型乳液体系,具有稳定性强、对环境友好、安全性高等天然优势。以板栗淀粉为主要原料,对其进行辛烯基琥珀酸酯化(octenyl succinic anhydride,OSA)改性,制备OSA改性板栗淀粉‐表没食子儿茶素没食子酸酯(epigallocatechin gallate,EGCG)‐Pickering乳液,再通过对不同EGCG添加量的乳液进行乳滴粒径、Zeta电位测定、体外模拟消化以及稳定性分析,探究其在各消化阶段的水解程度和稳定性。结果表明:模拟体外消化结束后,乳液在口腔和胃部的Zeta电位绝对值明显下降,在小肠内则有上升的趋势;稳定性分析表明:随着氯化钠浓度的增加,乳液的平均粒径逐渐增大;随pH值的增加,乳液的平均粒径先减小后增大,在pH6.0时达到最小。综上,通过将OSA改性板栗淀粉‐EGCG纳米微粒应用于Pickering乳液,可显著提高EGCG的稳定性。
