Phoenix Scientific Industries Ltd (PSI) has reported the successful development and scale-up of a process for coating 316L stainless steel powders with boron nitride nanoparticles for Additive Manufacturing applications.

According to PSI, its work addresses a longstanding challenge in powder engineering: achieving the uniform dispersion and application of nanoparticles onto metal powder surfaces at an industrially relevant scale. Nanoparticles have attracted interest for their potential to modify material properties and processing behaviour, but their tendency to form agglomerates has limited wider industrial adoption.
