The uppermost monolayers of a metal implant are far more important for the corrosion resistance than the alloy itself. Using electron spectroscopy for chemical analysis (ESCA) technique these oxide layers on Vitallium specimens were investigated regarding thickness, elemental composition, and valence state of the elements. The oxide layers on metal implants are not very strong, as they can be easily damaged mechanically. According to environmental conditions, oxide layers of different elemental composition can be grown on the same specimen.
金属植入物的最上层单分子层对耐腐蚀性的影响远比合金本身重要。利用化学分析电子能谱(ESCA)技术,对维塔利姆合金试样上的这些氧化层的厚度、元素组成和元素价态进行了研究。金属植入物上的氧化层不是很坚固,因为它们很容易受到机械损伤。根据环境条件,同一试样上可以生长出不同元素组成的氧化层。
