Aviation Engine Hot Section Protection Evolves: How to Validate High-Temperature Coatings on Turbine Blades?
From advances in ion-assisted multi-metal CVD coatings and 1200°C bond layers, to validation of thermal cycling, thermal shock, and temperature gradients. For coatings intended for hot-section engine service, "making them" is only the first step; their ability to withstand long-term oxidation, repeated thermal cycling, temperature gradients, and interfacial stresses determines whether they can operate reliably.
2.5D/3D Advanced Packaging Accelerates Adoption: Thermal Stress and Temperature Cycling Validation Become Critical
As advanced packaging evolves from "increasing interconnect density" to "system-level integration," reliability challenges expand from the individual chip level to thermal-mechanical coupling across chips, interposers, substrates, solder joints, and encapsulation materials. Thermal stress, warpage, and temperature cycling reliability are now critical determinants—not just of whether a package can be manufactured, but of whether it can operate stably over the long term.
