Feature of Rhenium-doped molybdenum powder ,MoRe0..5 molybdenum-rhenium alloy powder
-
High Melting Point: Molybdenum has one of the highest melting points among all pure elements, at 2,623°C (4,753°F). This property makes it ideal for high-temperature applications.
-
Strength and Toughness: Even at high temperatures, molybdenum maintains its strength and hardness, which is essential for use in extreme environments.
-
Corrosion Resistance: Molybdenum exhibits good corrosion resistance to many acids and alkalis, although it can be attacked by oxidizing acids like nitric acid.
-
Thermal Conductivity: It is an excellent conductor of heat, making it suitable for applications where efficient heat transfer is required.
-
Alloying Agent: Molybdenum is widely used as an alloying agent, particularly with steel, to enhance hardness, toughness, and resistance to wear and corrosion. Stainless steels often contain molybdenum for these properties.
-
Electrical Applications: Due to its low resistivity and high-temperature stability, molybdenum is used in electrical contacts and heating elements.
-
Lubricity: Molybdenum disulfide (MoS₂) is a common dry lubricant, providing low friction surfaces in high-pressure, high-temperature conditions.

Parameters of Rhenium-doped molybdenum powder ,MoRe0..5 molybdenum-rhenium alloy powder
The performance of the Rhenium-doped molybdenum powder, MoRe0.5 molybdenum-rhenium alloy powder can be influenced by several parameters, including the ratio of rhenium to molybdenum, the concentration of rhenium in the powder, and the impurities present in the powder.
Here are some general guidelines for optimizing these parameters:
1. Ratio of rhenium to molybdenum: The optimal ratio of rhenium to molybdenum depends on the specific application and desired properties. Generally, a higher ratio of rhenium to molybdenum (e.g., 2:1 or 3:1) can result in better strength and hardness, while a lower ratio can lead to a harder and more brittle material.
2. Concentration of rhenium in the powder: The concentration of rhenium in the powder affects its physical properties and magnetic properties. Higher concentrations of rhenium can improve both strength and, but may also increase the cost of the powder. Lower concentrations may result in weaker materials with less desirable properties.
3. Impurities present in the powder: The presence of impurities in the powder can affect its behavior and compatibility with other materials. In general, it is best to minimize the amount of impurities in the powder, as they can interfere with the bonding between rhenium and molybdenum and reduce the overall performance of the material.
Overall, the optimal conditions for using Rhenium-doped molybdenum powder, MoRe0.5 molybdenum-rhenium alloy powder, will depend on the specific application and desired properties. It is important to carefully analyze the relevant factors and optimize them through experimentation and simulations to achieve the best possible performance.
