Production of vacuum vessel
专利汇可以提供Production of vacuum vessel专利检索，专利查询，专利分析的服务。并且PURPOSE: To intensify the strength of a joint part by interposing an Al brazing material between a stainless steel vessel body provided with a high-purity Ni plating layer at an aperture end and Al material and brazing and joining the same.
CONSTITUTION: A flange 3 made of a stainless steel and the Al material 1 are grasped via the brazing material 2 interposed therebetween. Such assembly is heated in a vacuum or inert gaseous atmosphere by which the assembly is brazed and joined. The high-purity Ni layer 31 having ≥95% purity is preliminarily formed at 1W50μm thickness at the open end of the vessel body 4. Al-Si-0.2W3% Mg is used as the brazing filler metal for vacuum brazing and Al-Si-Be and Bi are used as the brazing filler metal for brazing in the inert gaseous atmosphere. The joint part obtd. in the above-mentioned manner has the high strength and withstands a high vacuum and is therefore applicable to an electronic tube such as X-ray receiving tube and others.
