XPS analysis for the C-SiC coatings before and after H~+ ion irradiation
【摘要】 对不锈钢基体上离子束混合沉积的C -SiC涂层进行了H+ 辐照模拟试验 ,由SIMS测量H+ 辐照前后氢的浓试分布 ,采用沟电子能谱 (XPS)对H+ 辐照前后涂层元素C和Si进行了内层电子结合能的测量分析 ,研究C及Si的化学键态的变化与H的关系 ,探讨SiC涂层阻氢机理
【Abstract】 Simulating experiments of H + irradiation were made for the C-SiC coatings deposited by ion beam mixing on stainless steel substrates. Hydrogen depth profiles of SIMS spectra were measured for the specimen before and after H + ion irradiation. XPS was used to analyze the chemical bonding energy for C and Si elements of coatings before and after H + ion irradation. Relationship between the changes of the chemical bond states for the elements of the C-SiC films and hydrogen was studied. Related mechanism of hydrogen resistant property for the C-SiC coatings was discussed.
