In the preparation process of TZM alloy rods, it is very important to ensure the purity of the material, the following are some common methods to improve the purity of the material:
Raw material selection: select high-purity raw materials as the starting material of the alloy to ensure that the purity of the raw materials meets the requirements. This can be achieved by selecting quality raw material suppliers and performing chemical analyses.
Clean process: During the preparation process, the entire process chain is kept clean to avoid contamination by impurities. Use clean equipment, tools and containers to prevent the introduction of foreign matter.
Melting technology: Using appropriate melting technology, such as arc melting, electron beam melting, etc., the melting and purification of materials at high temperature can be achieved. In the smelting process, control the smelting temperature, smelting time and the use of smelting agent to improve the purity.
Refining and Purification: Use refining agents or decontamination agents to remove impurities and increase the purity of the material. This can be achieved by adding suitable compounds or additives during the smelting process.
Heat treatment: Through appropriate heat treatment process, such as high temperature annealing, vacuum treatment, etc., the purity of the material can be further improved. Heat treatment can remove residual impurities and gases, adjust the grain structure, and improve the purity of the material.
Analysis and testing: Use advanced analysis and testing techniques, such as spectral analysis, chemical analysis, scanning electron microscope, etc., to control and verify the quality of the prepared materials to ensure that the purity of the materials meets the requirements.
