四、学术成果介绍
主要从事金属局部腐蚀机理及耐蚀合金理论设计研究,在最具代表性的点蚀研究领域取得了系列成果:(1)建立并验证了“一个观点、两大判据、三个模型”的点蚀生长统一理论,提出了点蚀最大溶解电流密度的新概念,搭建了微观参量(如金属键能)与宏观耐蚀性参数间的理论联系;(2)利用该理论,探索了耐蚀合金的计算设计方法,设计并制备了极端苛刻环境下对点蚀免疫的多主元素合金;(3)基于新理论,从点蚀生长稳定性出发阐述了过饱和间隙固溶体合金的微观耐蚀机理,提出了利用非金属间隙原子编织共价键网络提高合金耐蚀性能的设计思路。
在腐蚀领域重要期刊发表论文30余篇,其中以第一作者发表17篇,包括Corrosion Science 9篇、Journal of Electrochemical Society 5篇、Acta Materialia 1篇、Electrochimica Acta 1篇、Electrochemistry Communications 1篇,合作论文包含Nature Materials等。上述工作被国际腐蚀专家评价为“局部腐蚀领域近几十年最具创新性工作”、“具有极大的理论价值”、“促进了金属腐蚀电化学理论的发展”,并被多家科研媒体及腐蚀综述文章报导。
