Tómarúmdreifingarsuðuferli

        Vacuum diffusion suðu er suðuaðferð sem heldur nátengdum íhlutum undir ákveðnu hitastigi og þrýstingi í ákveðinn tíma í lofttæmu umhverfi, þannig að atómin milli snertiflötanna dreifast til að mynda tengingu. Þrátt fyrir að dreifingarsuðu sé suðuferli með langa sögu hefur það ekki þróast hratt fyrr en undanfarin ár. Suða þessa ferlis er ósýnileg með berum augum og engin þörf er á að bæta við lóðmálmi eða bræða efni. Jafnvel við mikla stækkun er erfitt að fylgjast með kristalfasabreytingunni. Eiginleikar dreifingarsuðuhluta hafa einnig samsvarandi sérstöðu meiri styrkleika, besta tæringarþol og engin krossmengun. Mörg ný forrit, þar á meðal orkuverkfræði, hálfleiðarar, verkfæri og loftrými, byrja að nota þetta sérstaka ferli vegna margra kosta þess.

Advantages of  Tómarúmdreifingarsuðu:

1. High joint strength. It is especially suitable for the welding of materials prone to cracks by fusion welding. Since the properties of the base metal are not changed, the chemical composition, microstructure and properties of the joint are the same or close to the base metal, and the joint strength is high.

2. There are many kinds of materials can be used. Diffusion welding can weld a variety of similar metals and alloys, as well as many different materials. If vacuum diffusion welding with transition alloy layer is adopted, heterogeneous or homogeneous materials with great differences in physical and chemical properties and easy to form brittle compounds at high temperature can also be welded.

3. It can be used for the manufacture of parts requiring large-area bonding, laminated members, hollow members, porous members or members with complex internal channels, closed internal assemblies and parts with poor accessibility of other welding methods.

4. Diffusion welding is integral heating, with small component deformation and high dimensional accuracy.

Umsóknir:

     Diffusion welding is mainly used for welding small, precise and complex weldments that are difficult to meet the quality requirements of fusion welding and brazing. In recent years, vacuum diffusion welding is more and more widely used in the manufacture of high-power liquid cooling plate . The advantages of small welding deformation and high dimensional accuracy make the liquid cole plate's structural has higher  reliability after welding.
