On August 1, 2026, a research team at Hiroshima University unveiled a hot-wire laser cladding technology for depositing WC-Co tungsten carbide coatings, achieving a hardness exceeding 1400 HV—comparable to conventional cemented carbides and significantly higher than standard laser-clad WC-Co coatings (around 1100 HV)—while also delivering more uniform WC particle distribution. The approach combines a heated wire (which preheats the substrate to reduce residual stress) with laser cladding (for precise energy control), addressing the long-standing issue of cracking in WC-Co deposition. WC-Co coatings are essential wear-resistant materials for molds, cutting tools, and mining machinery, representing a multi-billion-dollar global market. Industry significance: surpassing 1400 HV in WC-Co coating hardness marks the first time AM-produced coatings have matched the performance of traditional sintered cemented carbides. The hot-wire-assisted method resolves the persistent cracking problem in laser cladding of hard materials, opening a viable technical pathway for transitioning WC-Co from sintering to additive manufacturing. For powder buyers, if this technology scales from lab to production, it would generate new demand for spherical WC-Co powder (used in LPBF). While the current WC-Co powder market is niche, its high unit price ($80–150/kg) means that a technological breakthrough could substantially drive demand growth.
