In the aerospace field, iridium alloys have occupied a place for their excellent corrosion resistance and high temperature properties. However, with the retirement of aircraft engines and spacecraft, how to recover these precious iridium alloys has become a technical problem. This paper aims to describe innovative technologies for iridium alloy recovery in the aerospace field.
The initial step is to use specialized dismantling and sorting techniques to precisely separate components containing iridium from decommissioned spacecraft or engines. This process requires high precision and equipment advancement to ensure that the iridium alloy components are not damaged and remain recyclable.
Next, the iridium alloy is extracted from the complex components using high-temperature melting techniques or chemical treatments. High temperature smelting is the effective separation of iridium alloy from other materials by high temperature, while chemical treatment is to achieve the purpose of extraction by specific chemical reaction conditions or solvents.
In this process, the continuous innovation of technology and the continuous optimization of the process are the key to improve the recovery and purity of the iridium alloy. For example, the extraction efficiency and purity of iridium can be significantly improved by fine-tuning the melting temperature or chemical processing conditions.
The recovered iridium alloy is subjected to a series of rigorous quality control tests to ensure that its performance and quality meet the high standards of the aerospace industry. This includes thorough and detailed testing of its microstructure, mechanical properties and chemical composition to ensure its stability and safety in subsequent applications.
At the same time, through in-depth cooperation with leading companies in the aerospace industry, we actively promote this recycling technology, aiming to improve the efficient recycling of resources. This will not only help companies reduce production costs, but also help promote the entire aerospace industry to a more green and sustainable development path, thereby reducing the negative impact on the environment.
It is worth mentioning that the recovered iridium alloy can be reused to produce new engine or spacecraft components, thus reducing the mining of new mineral resources. This pattern of recycling is a sign that the aerospace industry is moving in a more environmentally friendly and sustainable direction.
