摘要
A reactive brazing of primary metallic element with secondary element containing ion-covalent oxide is performed using alloy designed to constitute liquid brazing alloy designed to wet two metallic and ion-covalent oxide surfaces of two elements. The content of titanium in brazing alloy is 2-5 wt.%, when the content of metal which can form intermetallic compounds with titanium is less than 20 wt.%. The content of titanium is 5-10 wt.%, when the content of metal which can form intermetallic compounds with titanium metal is 20-50 wt.%. Thus, assembly method is enabled. A reactive brazing of primary metallic element with secondary element containing an ion-covalent oxide on the surface is performed using alloy designed to constitute liquid brazing alloy designed to wet the two metallic and ion-covalent oxide surfaces of the two elements. The brazing alloy contains titanium and metallic element contains nickel. The content of titanium in the brazing alloy is 2-5 wt.%, when the content of the metal which can form intermetallic compounds with titanium is less than 20 wt.%. The content of titanium is 5-10 wt.%, when the content of the metal which can form intermetallic compounds with titanium metal is 20-50 wt.%. The content of titanium is 2-5 wt.%, when the content of metal which can form intermetallic compounds with titanium is more than 50 wt.%. The content of silver is less than 60 wt.%, such that the non-wettability area on the surface of the secondary element obtained from ion-covalent oxide with thickness and stable reaction layer at the interface of the element is minimized, and the formation of intermetallic compounds in the brazed joint is minimized. Thus, assembly method is enabled. An independent claim is included for vacuum cartridge, which has cylindrical component and two end cover plates, in which at least one is assembled to the cartridge component.
