Influencing Factors Of Temperature Field In Transformer Coil Curing Process
Shanghai Ghang Vacuum Technology Co., Ltd. explores the mutual influence factors between the temperature field and the stress field in the process of dry transformer pouring, curing and setting cycle.Because the temperature field is not uniform, thermal stress is generated, and part of the therma...
Introduction to the preparation method of amorphous/nanocrystalline composite materials
Formation of amorphous alloys Crystals are solids with regular geometric shapes formed through the crystallization process. They are formed by periodic arrangement of atoms or molecules according to a certain rule. Corresponding to a crystal, a solid with irregular arrangement of atoms or molecul...
Preparation of diamond/aluminum composite materials
Metal matrix composites have great advantages in heat transfer performance due to their special structure. Among them, diamond/aluminum composite material has become a research hotspot and development direction in the field of thermal management due to its advantages of low density, high thermal ...
Sintering and application of silicon carbide ceramics
Silicon carbide ceramic materials have the advantages of wear resistance, corrosion resistance, high hardness, low density and high high temperature strength, so they are rapidly popularized and developed in various fields in recent years. In aerospace, nuclear industry, petroleum industry, chemi...
Application of vacuum hot pressing sintering furnace
1. Advanced ceramic hot pressing sintering (B4C sintering) The densification sintering of pure boron carbide is extremely difficult because its covalent bond reaches 93.94%, which is much higher than that of silicon carbide (88%) and silicon nitride (70%). Therefore, the elimination of pores, gra...
SIC Ceramic Pressureless Sintering Production Process
Silicon carbide ceramics have stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance. In addition to being used as abrasives, there are many other uses, such as: coating silicon carbide powder on water turbine impellers or cylinder block...
