The pitting critical potential of the fresh surface is lower than that of the surface covered by passive film. At free-corrosion potential and anodic potential, the susceptibility to SCC was very low. 去膜表面发生点蚀的临界电位低于膜覆盖表面发生点蚀的临界电位。在自腐蚀电位和阳极电位条件下,SCC敏感性很低。
C-Si surface melting and α-Si/ Si film crystallization are simulated adopting Molecular-dynamics simulation method and S-W potential. 采用S-W势运用分子动力学方法对硅晶表面的熔化及α-Si/Si薄膜的晶化进行了模拟。
Monolayer techniques used for the study of surface film at the air-water interface provide a lot of information of film molecules, including optic microscope, x-ray, wave damping, spectroscopy, surface potential measurement, surface pressure measurement. 对表面膜的测量研究方法有很多,包括光学显微镜、X射线、波阻尼法、光谱方法、表面膜电位法、表面膜压法等。
Cr content had not only a relationship with the structure and thickness of surface oxidizing film, but also been largely considered for determining the corrosion potential difference between martix and carbides. 铬元素的含量不仅与表面氧化膜的结构和厚度有关,还在很大程度上决定了基体与碳化物的电极电位差。
