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...

Introduction to the characteristics of high-performance sintered rare earth NdFeB
Neodymium iron boron is a kind of rare earth permanent magnet compound, composed of rare earth metal neodymium, metallic element iron, non-metallic element boron and a small amount of praseodymium, dysprosium, niobium, aluminum, gallium, copper and other elements. It is a kind of magnetic materi...
H13 heat treatment process and vacuum heat treatment equipment
H13 is American H series hot work die steel, similar to China 4Cr5MoSiV1 (GB) steel grade, while China Cr12Mo1V (GB) is a ledeburite steel, similar to American AISI and ASTM standard steel grade D2. The two are completely different. H13 is hot For die steel, the final heat treatment is generally ...
Application of vacuum pump system in vacuum heat treatment
Points to note for heat treatment of vacuum pump system: 1. When disposing of titanium alloys in a vacuum furnace, nitrogen should not be used as a cooling gas, because titanium and nitrogen react at high temperatures to form golden-yellow titanium nitride. 2. The movable connection part of the v...
