How is the production process for sintered titanium filter?
The production process of sintered titanium filters involves a number of procedures, which need to be combined with raw material handling, melting, plastic processing and quality control, etc. The following is the integration and analysis of the standardized process:
As the core raw material, need to screen high-purity titanium sponge (Fe ≤ 0.30%, O ≤ 0.25%), some alloys need to add aluminum, molybdenum, niobium and other elements. Alloy ratio: such as β titanium alloy needs to be mixed by weight percentage (such as Mo 4-7%, Nb 4-6.5%, Al 1-4%).
Titanium sponge and alloy powder are pressed into block electrode by hydraulic press, and welded into long electrode by ion welding.
In a vacuum or inert gas environment, the electrode is melted at 1700-1950 ℃ to remove impurities and form titanium ingots. Multiple melting: usually repeated 2-3 times to enhance compositional homogeneity (e.g., β-titanium alloy requires 3 melts).
Temperature control: Titanium ingot is heated to 950-1100℃ for open billet forging to break the cast organization and refine the grain. Multi-directional forging: Improve the organization uniformity by forging in different directions, and reduce the subsequent rolling deformation.
Hot rolling: initial rolling at 900-1000 ℃ to form cylindrical blanks (such as 500mm diameter titanium rods). Cold rolling: finishing rolling at room temperature to improve the dimensional accuracy (e.g. thin-walled tubes, capillary tubes).
Selection of die forging: open die forging with high loss (15-20% burr), closed die forging requires precise control of the volume of the blank.
Acid washing: use hydrofluoric acid - nitric acid mixture (acid concentration ≤ 6%) to remove the oxide skin, resulting in acid mist (G2) and waste acid residue (S5). Water washing: remove residual acid and grease, generate oily waste water (W1/W2).
Annealing: 700-800 ℃ annealing to eliminate internal stress, some alloys need to solid solution aging (such as 950 ℃ solid solution + 550 ℃ aging). Straightening: Correct the shape by straightening machine and generate noise (N5).
Chemical analysis: ICP spectrometer to detect impurities (e.g. Fe, O content). Mechanical test: Tensile strength (TA1: 240MPa, TC4: 895MPa), elongation, etc.
Ultrasonic flaw detection (UT): detect internal cracks, pores and other defects.
Polishing (Ra≤0.8μm) or spinning treatment to enhance the finish.
Moisture-proof and shock-proof packaging, generating waste packaging materials (S8).

Frequently Asked Questions (FAQ)
Sintered titanium filters offer high strength with a lightweight profile (density of 4.5g/cm³), excellent corrosion resistance to strong acids, alkalis, and seawater, superb biocompatibility, high-temperature stability up to 540°C, and excellent processability like welding and 3D printing.
These filters and components are highly utilized in aerospace (engine blades and fuel tanks), healthcare (artificial joints and dental implants), chemical energy (reactors and nuclear cooling), marine engineering, automotive manufacturing, and sports equipment.
Specifications are generally divided by diameter: small diameters (<10mm) are ideal for medical devices and precision electrodes; medium diameters (10-100mm) suit chemical equipment and ship parts; large diameters (>100mm) are used for nuclear power equipment and heavy machinery.
Yes. To maintain performance, avoid scratches and oil contamination. Regularly clean the surface with water or a neutral detergent. In highly corrosive environments, it is recommended to inspect the surface condition every 2 years.
The cost is driven by raw materials (titanium sponge accounts for 60% of the cost) and the complex manufacturing processes required, such as vacuum self-consumption arc melting (VAR) and multi-directional forging, to achieve exceptional performance characteristics.
In conventional environments (like building structures), titanium rods can last for more than 20 years. In highly corrosive environments (like chemical pipelines), their service life ranges between 8 and 15 years.
