How to Specify Boron Carbide Powder: Purity, Particle Size, and B/C Ratio
A single-digit percentage error in specifying boron carbide (B₄C) powder can push a ballistic armor insert outside its V50 envelope or cause a lapping slurry to scratch an optic beyond salvage. Incorrect purity, an overlooked bimodal particle size distribution, or a misjudged B/C atomic ratio routinely leads to premature component failure and unbudgeted line downtime. […]
SG Abrasives in Vitrified Grinding Wheels for Bearing Steel Production
Specifying the wrong abrasive grain for bearing steel grinding doesn’t just slow cycle times—it risks subsurface microcracking that propagates into premature spalling under cyclic load. In high-volume production of AISI 52100 and similar through-hardened steels, maintaining a cool, self-sharpening cut while holding sub-micron roundness tolerances defines process viability. This article dissects how sol-gel (SG) ceramic […]
