投资铸造业务可以受益于在生产涡轮发动机叶片生产的核心支撑杆中较短的浸出周期，此后开发了一系列新材料，这些材料已专门为此目的优化，而不是石英或氧化铝替代品。亚博网站下载
Developed by global materials leader Morgan Advanced Materials, the LEMA™ range of proprietary alumina-based materials will play a vital role in maximising throughput and capacity for turbine blade manufacturers. While typical alumina rods are renowned for their strength and load bearing capabilities, it can take several days to fully leach the materials, resulting in delays within the production process.
At a time when demand for turbine engine blades is expected to grow substantially over the next few years, based on the ramping build schedules of new engine programs such as CFM’s LEAP engine and Pratt and Whitney’s PurePower™ PW1000G family of engines, the enhanced leachability of LEMA™ rods shortens processing times significantly, allowing manufacturers to produce more components.
与氧化铝相比，Lema™的渗滤液性的提高，浸出过程通常更具挑战性，可以通过提高初次传球收益率来节省成本和时间。此外，它可以与较不侵略性和更易于用户友好的浸出解决方案一起使用，有助于克服与使用更具侵略性物质相关的成本和健康与安全限制。
While quartz offers a cost-effective alternative to alumina in terms of leachability, it lacks the strength of alumina, making it less suitable for applications where part geometries and alloys require higher strength support rods. LEMA™ components are approximately 1.5 times stronger than quartz equivalents, resulting in higher quality castings with fewer defects.
