Past thermal protection prioritized temperature resistance. Today, with commercial aerospace and energy storage scaling up, cost per kilogram has become the deciding factor. This article explores how to balance cost and performance.

At the intersection of precursor-derived ceramics and high-entropy ceramics, PHEC addresses a key question: Can we maintain high-temperature performance while significantly reducing costs? This article outlines its technical approach and validation pathway.

Why do high-performance coatings fail over time? The answer isn't sudden failure, but a gradual process starting from invisible micro-cracks and ending in widespread peeling. Understanding this progression is key to understanding coating lifespan.

An experienced technician can spot a coating's condition with just a flashlight, but when dealing with thousands of parts, human eyes aren't enough. Can AI vision perform a "check-up" on materials to detect subtle internal damage?

Is it better to repair a damaged heat shield or replace it entirely? Repair isn't always cost-effective; the heavier the damage, the higher the repair cost. Beyond a certain threshold, replacement becomes cheaper than repair. Identifying this tipping point is key to reusability economics.

Traditional maintenance often replaces parts at fixed intervals, risking premature waste or delayed failure. Condition-Based Maintenance (CBM) determines repair timing based on the actual material condition—provided that condition can be accurately measured and assessed.

Whoever sets the standard holds the voice. The thermal protection sector has long lacked a unified, public evaluation standard. Filling this gap is critical for China's thermal protection industry to transition from following to leading.
