Platinum Target Advantages

• High purity ensures the coating layer's consistency, which is crucial for manufacturing precision electronic devices.
• It has a high melting point and good thermal stability, and can still maintain structural stability in high-temperature environments.
• It has high density, good hardness, and excellent wear and scratch resistance.
• Excellent electrical and thermal conductivity can effectively dissipate heat and reduce the risk of electron beam thermal damage.
• Its extreme chemical inertness makes it less prone to volatilization or contamination of samples under vacuum and electron-beam bombardment.
• The high atomic number allows it to produce high-intensity characteristic X-rays, significantly improving detection sensitivity and contrast in backscatter electron imaging.

3. New energy: The prepared catalyst coating is used in hydrogen fuel cells, which can significantly improve energy conversion efficiency.
4. Aerospace: Turbo blade TBC bonding layer and combustion chamber wall coating for aero engine hot-end components through electron beam physical vapor deposition technology
5. Analytical technology: Generate high-intensity characteristic X-rays as an excitation source in X-ray energy spectroscopy analysis equipment to improve the detection sensitivity of light elements (C, O).

Processing

1. Smelting and casting

(1) The high-purity platinum raw materials are melted under vacuum or inert gas protection by vacuum induction melting or electron beam melting. Subsequently, the molten platinum is cast into the mold to form a platinum ingot.

(2) Hot forging or hot rolling of platinum ingots to preliminarily refine the grains and increase the density. After that, it is cold rolled in multiple passes to process it into a plate or foil close to the target thickness.

2. Powder metallurgy

(1) Fill the high-purity platinum powder into a metal sleeve, then vacuum and seal.

(2) The sealed bag is placed in a hot isostatic press for sintering to form a billet with a very high density (≥99.5%).

(3) The sintered billet is de-sheathed, forged, and rolled to further control the grain size and final shape, and finally optimize the performance through heat treatment.

3. General follow-up processing

(1) Through precision machining such as turning, milling, grinding, and polishing, the platinum sheet is processed into the exact size and shape required by the customer, and the surface roughness is ensured to be extremely low
(2) Ultrasonic cleaning: Use anhydrous alcohol and other solvents for ultrasonic cleaning to thoroughly remove oil stains and tiny particles on the surface to avoid pollution during the coating process.
(3) Quality inspection: such as purity testing, visual inspection, dimensional accuracy, non-destructive testing, etc.
(4) The finished target will be vacuum-sealed and packaged in a clean environment to prevent oxidation or contamination during transportation and storage.
