Vakuumli diffuziyali payvandlash jarayoni

        Vakuumli diffuziyali payvandlash payvandlash usuli bo'lib, bir-biriga yaqin bog'langan komponentlarni ma'lum bir harorat va bosim ostida vakuum muhitida ma'lum bir vaqt davomida ushlab turadi, shuning uchun aloqa yuzalar orasidagi atomlar birikma hosil qilish uchun tarqaladi. Diffuziyali payvandlash uzoq tarixga ega bo'lgan payvandlash jarayoni bo'lsa-da, so'nggi yillargacha tez rivojlanmagan. Ushbu jarayonning payvandi yalang'och ko'z bilan ko'rinmaydi va lehim yoki erituvchi materialni qo'shishning hojati yo'q. Yuqori kattalashtirish sharoitida ham kristall faza o'tishini kuzatish qiyin. Diffuziyali payvandlash qismlarining xarakteristikalari, shuningdek, yuqori quvvat, eng yaxshi korroziyaga chidamlilik va o'zaro ifloslanishning mos keladigan o'ziga xosligiga ega. Ko'pgina yangi ilovalar, jumladan, energiya muhandisligi, yarimo'tkazgichlar, asboblar va aerokosmik, ko'plab afzalliklari tufayli ushbu maxsus jarayondan foydalana boshlaydi.

Advantages of  Vakuumli diffuzion payvandlash:

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.

Ilovalar:

     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.
