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...
Molybdenum alloy molding sintering
Molybdenum and molybdenum alloy have high high temperature strength and hardness, good thermal conductivity and electrical conductivity, low coefficient of thermal expansion, excellent wear resistance and corrosion resistance, are widely used in aerospace, energy, electricity, microelectronics, b...
vacuum heat treatment furnace price
Vacuum heat treatment furnace means that all and part of the heat treatment process are carried out in vacuum state. Vacuum heat treatment can realize almost all of the conventional heat treatment processes, but the quality of heat treatment is greatly improved. Compared with the conventional hea...
Oil quenching vacuum heat treatment furnace
Oil quenching vacuum heat treatment furnace: the use of vacuum quenching oil as a cooling medium furnace, known as oil quenching vacuum heat treatment furnace. Vacuum heat treatment with vacuum quenching oil, can not use ordinary cooking oil, otherwise, it can not achieve the purpose of vacuum qu...
vacuum heat treatment furnace type
The basic classification of vacuum heat treatment furnace there are many kinds of vacuum heat treatment furnace. In order to facilitate the analysis and comparison and reasonable selection and use, the following characteristics are generally classified: It can be divided into: vacuum annealing fu...
External vacuum heat treatment furnace
Advantages of external vacuum heat treatment furnace: (1) the structure is simple, easy to manufacture and easy to operate and maintain. (2) the volume of the vacuum tank is small, there are only processed workpieces in it, and the air volume is small, so it is easy to reach the required vacuum d...
Vacuum brazed diamond cutting disc
The brazing property of diamond is poor, and the main difficulties are as follows: 1. Most commonly used solder is difficult to be wetted or cannot be wetted. 2. The linear expansion coefficient of diamond is lower than that of most metal materials, and it is easy to change its properties under t...
