Dispersion strengthened material used for platinum-based vessel and preparation method and application of material
A dispersion-strengthening, utensil technology, applied in the direction of metal material coating process, coating, fusion spraying, etc., can solve the problem that the anti-deformation, anti-erosion, anti-corrosion performance cannot meet the expected requirements, and the production cost of optical glass and glass fiber is high. High temperature, easy to creep deformation and other problems, to achieve the effect of good erosion resistance and corrosion resistance, excellent high temperature durability and high temperature creep resistance, and high compactness

Example Embodiment
[0051] Example 2
[0052] Platinum: 998.5g (weight percentage 99.85%), zirconium: 0.5g (weight percentage 0.05%), scandium: 0.5g (weight percentage 0.05%), cerium: 0.05g (weight percentage 0.05%).
Example Embodiment
[0053] Example 3
[0054] Platinum: 997g (99.7% by weight), zirconium: 3g (0.3% by weight).
[0055] Prepare the dispersion-strengthened material for platinum-based utensils according to the following method:
[0056] (1) Allocation of raw materials
[0057] Take the ingredients described in Examples 1-3;
[0058] (2) Vacuum intermediate frequency melting
[0059] Put the prepared raw materials into a vacuum furnace for melting, the melting temperature is 1800~1900℃, and the vacuum degree is 10 -2 -10 - 3 Pa, while being filled with argon gas protection, after the raw materials are completely melted, magnetically stirred uniformly and kept for 2-5 minutes, the obtained liquid metal is quickly cast in a water-cooled copper mold to obtain an ingot;
[0060] (3) Thermal processing
[0061] The obtained ingot is uniformly heat treated at 1200°C for 30 minutes, hot forged into a rod shape, homogenized heat treated at 1200°C for 30 minutes, and subjected to stress relief annealing to obtain an a...
