Quality control is implemented throughout the entire production process. The specific measures for controlling quality during the production of cleaned tungsten wire are as follows:
- Raw Material Inspection: Analyze the purity of scheelite or tungsten powder and control impurity content (e.g., Fe, Mo < 0.01%).
- Doping Uniformity: Ensure uniform distribution of dopants through chemical analysis.
- Blank Inspection: Check the density and internal defects (e.g., pores, cracks) of sintered tungsten blanks.
- Dimensional Accuracy: Monitor tungsten wire diameter tolerance using laser diameter gauges or microscopes.
- Surface Quality: Inspect surface smoothness and defects using roughness testers or SEM.
- Mechanical Properties: Test tensile strength, elongation, and high-temperature creep resistance.
- Process Parameter Monitoring: Real-time recording of temperature, drawing speed, annealing time, etc., to ensure consistency.
- Final Inspection: Conduct batch sampling of finished products to test electrical properties (e.g., resistivity) and high-temperature stability.
