Could a dual-layer metallic coating be an innovation in jet-engine design? There is a line of innovation from product design to metallurgy, to production, and to product performance. For aerospace and defense systems, precision parts that operate under intense heat and high pressure are critical to performance and reliability. In this episode of Great Question: A Manufacturing Podcast, American Machinist chief editor Robert Brooks explains how researchers are proposing a new coating process that will make alternative, high-entropy alloys perform at significantly higher temperatures – which could mean greater fuel efficiency and lower maintenance costs for jet engines.
