choosing the right vacuum sintering furnace
In recent years, the application scope of vacuum sintering furnace has gradually expanded from scientific research and military industry to general industry. The main reason lies in the improvement of research and development strength of various enterprises and the higher requirements of research...
how to aluminum brazing
Many aluminum alloys can be joined by brazing. The brazing of aluminum is more difficult than that of other metals, because the melting points of metal and filler are close, and because of the oxide layer on the surface of aluminum. Aluminum alloys that can be brazed include 3003 and 60 series al...
vacuum hot pressing sintering furnace structure and application
For the sintering of metal, ceramic and some refractory metal intermetallic compound powder, two sintering methods are generally adopted, namely pressureless sintering and pressured sintering. At present, there are three main ways of pressure sintering, hot isostatic pressing sintering, hot press...
High pressure gas quenching
For many years, gas quenching has been the preferred process for steel heat treatment. Nowadays, high pressure gas quenching is the most powerful solution in the field of high alloy steel to alloy steel. SIMUWU vacuum furnace manufacturer proposed low pressure carburizing equipment, and this solu...
Vacuum heat treatment and traditional heat treatment
Vacuum heat treatment is a combination of vacuum technology and heat treatment, which means that all and part of the heat treatment process are carried out under vacuum. Vacuum heat treatment can almost achieve all heat treatment processes, such as quenching, annealing, tempering, carburizing, ch...
Preparation technology and solution of boron carbide bulletproof ceramics under hot pressure
Boron carbide is a new type of non-oxidized ceramic material, which is widely used in energy, military, nuclear and bulletproof fields due to its high melting point, high hardness, low density, good thermal stability, strong resistance to chemical erosion and strong neutron absorption. Boron carb...
Ceramic/metal connections and applications
Although the special ceramic materials have excellent insulation (most ceramics), high temperature resistance, corrosion resistance and wear resistance, but their brittleness and machining performance are very poor, it is difficult to prepare large or complex structural parts. Metal materials hav...
Heat treatment technology to improve the quality of die and machinery
1. Mold manufacturing accuracy Uneven and incomplete structural transformation and excessive residual stress caused by heat treatment cause deformation in the processing, assembly and use of the mold after heat treatment, thus reducing the precision of the mold or even scrap. 2. The strength of t...
High temperature annealing treatment of silicon carbide crystal
The most common and mature method for SiC crystal growth is still physical gas phase transport (PVT), which is a gas-phase growth method with high growth temperature and high requirements on raw materials and process parameters. In recent years, a great deal of time and energy have been invested ...
Vacuum brazing scheme of stone carving cutter
Stone carving knife is a special tool used in CNC stone carving machine. The special nature of stone determines that the stone carving knife must have the characteristics of high structural strength and high wear resistance. About the diameter of the tool handle: the selection principle of the di...
