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...
Ion nitriding
Ion nitriding also known as “glow ion nitriding” is a heat treatment process, it has the advantages of short production cycle, high surface hardness of parts, can control the brittleness of nitriding layer. Therefore, in recent years, domestic development is rapid, the use of a wide r...
Vacuum gas nitriding furnace
Vacuum nitriding furnace has a wide range of applications, including gas and ion nitriding, which needs to be done after vacuuming, so the effect is better. Ordinary nitriding furnace is suitable for small batch workpiece processing, using liquid nitriding, usually salt bath heating nitriding. Ga...
Sintering process of tungsten steel punch
Tungsten steel punch sintering molding is to press the powder into billet, then into the sintering furnace heating to a certain temperature (sintering temperature), and maintain a certain time (holding time), and then cool down, so as to obtain the required function of tungsten steel punch.The si...
