Vacuum Brazing Furnace for Aluminum Alloy Radiator
With the continuous growth of national economy and the continuous improvement of science and technology, the development of industrial industry has made a qualitative leap. As an advanced cooling equipment, aluminum alloy plate fin radiator is widely used in various industries. Its remarkable adv...
2500 ℃ high temperature vacuum furnace
In the field of vacuum equipment, due to the strict technical requirements of metal hot zone vacuum furnace equipment above 2000 ℃ on hot zone and corresponding peripheral protection measures, the market of ultra-high temperature vacuum furnace equipment above 2000 ℃ has been monopolized by Japan...
Reaction sintering silicon carbide ceramic sintering
Reaction sintered silicon carbide is a process that the raw materials (silicon carbide powder, graphite, carbon black, binder and various additives) pass through the solid phase at 1720 ℃, and chemical reactions take place between the liquid phase and the gas phase. At the same time, densificatio...
Three Methods Of Sintering Silicon Carbide Ceramics
1) No pressure sintering In 1974, GE company in the United States attempted to add a small amount of B and C to high-purity beta-SIC fine powder, and successfully obtained high-density SiC ceramics at 2020°C by using the pressure-free sintering process. The process has become the most important m...
The Difference Between Bonded Ndfeb And Sintered Ndfeb
1,Bonding Ndfeb Bonded ndfeb, Nd2Fe14B composition, is a synthetic magnet. Bonded NdFeB magnets are magnets made of a mix of quickly quenched NdFeB magnetic powder and binder through “pressed molding” or “injection molding”. The size precision of bonding magnet is high, wh...
Samarium cobalt magnet sintering
SmCo permanent magnet is an excellent permanent magnet material with high magnetic properties, strong corrosion resistance, oxygen resistance, low temperature coefficient, high Curie temperature, and can be used at a higher ambient temperature. Samarium cobalt sintered products are mainly used in...
Vacuum carburizing
Carburizing of steel is a widely used surface chemical heat treatment technology. After carburizing and quenching, a carburizing layer with high hardness and wear resistance is formed on the surface of steel, while the core maintains sufficient strength and toughness. Though carburizing in tradit...
Well type gas nitriding furnace
Working principle of well gas nitriding furnace The shaft type nitriding furnace is a periodic operation type electric furnace. It is an improved energy-saving electric resistance furnace based on the series of electric furnaces combined with the actual use of users. The maximum working temperatu...
Cost analysis of various nitriding methods in vacuum furnace
1. The structure of the vacuum gas nitriding furnace is complex, the price is a little higher, and the operation is a little more difficult. However, the nitriding quality is good, which can reach a very deep layer and high hardness, but it takes a long time, and the amount of ammonia gas is also...
Liquid nitriding
Liquid nitriding is a relatively new chemical heat treatment process, the temperature is not more than 570 ℃, the treatment time is short, only 1-3H; and it does not need special steel. The test shows that the anti-wear ability of 40Cr treated by liquid nitriding is 50% higher than that of genera...
