High temperature liquid sintering method.
Therefore, when the sintering method to grasp in order to achieve the best effect sintering. .
Ultrafine/ nano-alloy powder sintering method directly;
High-temperature sintering method using the material made of high relative density, good overall performance.
Tungsten copper mechanical alloying is a kind of sintering method by high-energy ball milling.
The method of preparation is mainly divided into two categories:infiltration and direct sintering method.
Existing tungsten copper sheet sintering method include the following: 1.
MA(Mechanical Alloying): After high-energy ball milling and other processing and to achieve the mechanical alloying between tungsten andcopper tungsten copper powder corresponding sintering method.
Up to the sixties, the only sintering method used in practice was direct sintering. .
Currently, most of tungsten copper alloy materials fabricated by powder mixing,pressing, sintering method of infiltration.
The use of high-temperature sintering method of manufacturing the material relatively high density, good overall performance.
Mechanical alloying: Tungsten copper mechanical alloying is a kind of sintering method by high-energy ball milling.
The name suggests, a direct sintering method, after forming the desired composition of the mixed powder of tungsten and copper repression directly sintered product.
As there is a huge distance between the tungsten and copper of the melting point,so we can adopt high temperature liquid sintering method to make tungsten copper alloy, through which densificate its density at the temperature higher than copper melting point.
Mixed powder sintering method is based on the required ingredients mixed molybdenum-copper alloy molybdenum powder and copper powder, and then molding, sintering directly into products.
Tungsten copper material with low oxygen content, high purity,high temperature sintering method suitable for the manufacture of copper mass fraction φ(Cu) is not greater than 15% of the tungsten copper material.
The sintering method of tungsten copper plate are different with the method of tungsten copper sheet, due to the thickness of the tungsten copper plate is much larger than tungsten copper sheet.
This method produces tungsten copper material, copper distribution along the tungsten grain boundaries,tungsten skeleton strength than high-temperature sintering method, such as this method as the contact material in the circuit breaker, easy to produce ablation.
Compared with the high-temperature liquid-phase sintering method, which not only reduces the sintering temperature and shortening the sintering time and the sintering density is greatly increased.
Wherein nickel based tungsten carbide powder prepared by atomization has a good spraying performance, uniform layer chemical composition, no macro-segregation, and tungsten carbide in it is not easily oxidized, but WC content should not be too high; preparation of mechanical mixing method can greatly improve the WC content, however,followed by a coating of segregation increasing; sintering method results in small composition segregation is, but with the highest cost.
Compared with conventional sintering method, sol gel method products with high uniformity and high purity, the temperature is 400°C~500°C lower than conventional sintering method, the reaction process is easy to control, can greatly reduce the side effects of the new phase formed.
Copper Tungsten Alloy Contact Parts As there is a huge distance between the tungsten and copper of the melting point,so we can adopt high temperature liquid sintering method to make tungsten copper alloy, through which densification its density at the temperature higher than copper melting point.
High temperature liquid sintering method As there is a huge distance between the tungsten and copper of the melting point, so we can adopt high temperature liquid sintering method to make tungsten copper alloy, through which densificate its density at the temperature higher than copper melting point.
Tungsten Copper Heat Sink Activation Strengthen Liquid Phase Sintering Method Since the high-temperature liquid-phase sintering can not be obtained near the theoretical density of tungsten copper electronic packaging sheet material, after sintering if the auxiliary handle, not only make the process complex and costly.
