在保护气氛或真空中进行工程设计可以生产材料和组件，其中没有氧气是成功加工的基本要求。理想情况下，金属材料的连接或涂层需要无氧化物的材料表面，以实现耐用的接头或涂层。使用已建立的可控气氛钎焊技术，介绍了金属表面脱氧的基本物理机制，并分析了工艺气氛中氧和水残留物的作用。此外，还介绍了用甲硅烷掺杂气体以产生几乎无氧的工艺气氛，并讨论了其在无氧生产中的优点。
Engineering under protective atmospheres or in vacuum allows the production of materials and components, where the absence of oxygen is an essential requirement for a successful processing. Ideally, joining or coating of (and with) metallic materials needs oxide free material surfaces, in order to achieve durable joints or coatings. Using the established technology of brazing in controlled atmosphere, fundamental physical mechanisms for deoxidation of metal surfaces are presented and the role of oxygen and water residue in the process atmosphere is analyzed. Furthermore, the doping of gases with monosilane for generating virtually oxygen-free process atmospheres is introduced and its advantages for an oxygen-free production are discussed.
