The process of producing tungsten-molybdenum alloy by powder metallurgy mainly includes the following steps:
Raw material preparation
First, high-purity tungsten powder and molybdenum powder are selected as raw materials to ensure the purity of the raw materials. Subsequently, the two powders are mixed in a predetermined ratio to obtain a uniform tungsten-molybdenum mixed powder.
Powder mixing
Use mechanical mixing methods such as ball milling or stirring to fully mix the tungsten powder and molybdenum powder to ensure the uniformity of the alloy composition.
Pressing and molding
Put the uniformly mixed tungsten-molybdenum powder into a mold, and press the powder into the desired shape and size by cold pressing or hot pressing technology. This process can ensure close contact between the powder particles and lay the foundation for the subsequent sintering process.
Sintering treatment
After pressing and molding, the blank is placed in a sintering furnace for sintering. At high temperature, a solid-phase reaction occurs between the powder particles, and a dense tungsten-molybdenum alloy material is formed through atomic diffusion and bonding. Parameters such as sintering temperature, time and atmosphere need to be precisely controlled according to the alloy composition and performance requirements.
Post-treatment
After sintering, the tungsten-molybdenum alloy is subjected to necessary post-treatment, such as grinding, cutting, heat treatment, etc., to obtain the final alloy product. These post-treatment steps help to improve the surface quality and performance of the alloy.
Through the above steps, the powder metallurgy method can produce tungsten-molybdenum alloys with high performance and uniform composition. This method has the advantages of high production efficiency, high material utilization rate and low cost, so it has been widely used in industrial production.
The preparation process of tungsten-molybdenum alloy is affected by many factors, such as raw material purity, powder particle size, pressing pressure, sintering temperature, etc. Therefore, in actual production, the preparation process needs to be optimized and adjusted according to the specific situation to obtain the best alloy performance.
