发明的背景1、发明的范围本发明的范围是铝连接件的焊接,更确切地说,是阐述铝连接件的扩散焊和钎焊。2、以前方法的简介由于铝的固有物理性能,所以用铝及其合金来制作某些部件是极有吸引力的。众所周知,铝有高的导热性、导电性、耐蚀性和特有的反射能力,故成为特别引人注目的材料,用来制造加热和冷却系统、热反射面和发动机零件等结构件和装配件。已发现,铝合金尤其适于制作宇宙飞船的散热板。尽管铝有许多良好的性能,但铝及其合金在焊接上还存在着特殊的困难。大家知道,置于大气中的铝,能很快在表面上形成一层难熔的铝氧化膜。实际上,该膜是如
BACKGROUND OF THE INVENTION 1. Scope of Invention The scope of the present invention is the welding of aluminum connectors, and more specifically, the diffusion bonding and brazing of aluminum connectors. 2, the introduction of the previous method Due to the inherent physical properties of aluminum, so the use of aluminum and its alloys to make some parts is very attractive. As we all know, aluminum has high thermal conductivity, electrical conductivity, corrosion resistance and unique reflectivity, it becomes a particularly attractive material for the manufacture of heating and cooling systems, heat reflecting surfaces and engine parts and other structural parts and assemblies. It has been found that aluminum alloys are especially suitable for the production of spacecraft heat sinks. Despite the many good properties of aluminum, there are particular difficulties in welding aluminum and its alloys. We all know that the atmosphere of aluminum, can quickly form a layer of refractory aluminum oxide film on the surface. In fact, the film is like
