The preparation processes of tungsten-molybdenum alloy mainly include the following methods:
Powder metallurgy method
Tungsten powder and molybdenum powder are mixed in a certain proportion, and can be mixed by ball milling or other powder mixing equipment to ensure the uniformity of the composition.
Put the mixed powder into a mold, press and form it, and then sinter it. During the sintering process, a solid-phase reaction occurs between the powder particles to form a dense alloy material.
Infiltration method
Molybdenum powder is placed in a tungsten matrix with a high porosity.
The molybdenum powder is infiltrated into the tungsten matrix through a sintering process to form a tungsten-molybdenum alloy material. This method can achieve a uniform distribution of tungsten and molybdenum and improve the performance of the alloy.
Melting method
Tungsten and molybdenum are heated to the melting point and then mixed and melted. This step requires precise control of the temperature and melting process to ensure the uniformity of the alloy composition.
Pour the mixed molten tungsten-molybdenum alloy liquid into a cooling mold for solidification. The alloy material obtained after solidification has a dense structure and good performance.
These preparation processes can be selected according to the specific alloy composition, shape and size, and application requirements. In addition, in order to improve the performance and processing properties of tungsten-molybdenum alloys, the preparation process can also be optimized and improved, such as by adding other elements or using special heat treatment processes.
In the preparation process of tungsten-molybdenum alloys, the purity of raw materials and preparation conditions need to be strictly controlled to ensure that the quality and performance of the alloy meet the requirements. At the same time, the performance of the prepared alloy needs to be tested and evaluated to meet the needs of practical applications.
