HEAT-RESISTANT IR-PT ALLOY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18143654 titled 'HEAT-RESISTANT IR-PT ALLOY
Simplified Explanation
The patent application describes a heat-resistant alloy made of iridium (Ir) that has improved hardness and processability.
- The alloy consists of 5% to 30% platinum (Pt), 0.5% to 5% tantalum (Ta), and 0.003% to 0.15% of either scandium (Sc), hafnium (Hf), or tungsten (W).
- The remaining balance of the alloy is iridium.
- The alloy is designed to withstand high temperatures while maintaining its hardness.
- The addition of platinum and tantalum improves the alloy's heat resistance.
- The inclusion of scandium, hafnium, or tungsten further enhances the hardness of the alloy.
- The alloy is also easy to process, making it suitable for various applications.
Original Abstract Submitted
