Description
Chunmei Wen and co-authors find that how you mill the powder decides how tough a super-hard ceramic turns out in this 2024 study. Their material blends four metal carbides into one high-entropy ceramic plus silicon carbide, a mix prized for cutting and wear parts. Five carbide powders were milled either dry or wet, then fused under pressure and heat.
Both versions formed, but the wet-milled ceramic came out finer and more even, with grains under two micrometers. It was harder, resisted cracking better, and wore away far more slowly in friction tests. A thin oxide skin that formed while rubbing helped protect its surface. The dry-milled version lagged on each measure. The authors name the wet-milled ceramic a strong candidate for wear-resistant parts, and credit the milling step, often treated as routine, for the gap.
