This proposal is directed to understanding metal-ceramic interfacial reactions and how they are influenced by chemical segregation and defects at the ceramic surface. Initial focus is on alumina and silica surfaces and use of dopants to modify surface properties. Bonding to both reactive and noble metals are examined; examples include titanium, gold and platinum. X- ray photoelectron spectroscopy (XPS) is used to study composition and chemical states at the surfaces.

这一建议旨在了解金属-陶瓷界面反应，以及它们如何受到化学偏析和陶瓷表面缺陷的影响。最初的重点是氧化铝和二氧化硅表面和使用掺杂剂来改变表面性质。检查了与活性金属和贵金属的键合；例如钛、金和铂。X射线光电子能谱（XPS）用于研究材料表面的成分和化学状态。
