RAZOR BLADES WITH CHROMIUM BORIDE-BASED COATINGS

This invention relates to a novel application of a compound of chromium and boron, or the application of chromium boride-based coatings (e.g., CrBn where an atomic percentage of boron ranges from greater than zero atomic percent to less than 100 atomic percent of said compound) to surfaces of razor...

Beschreibung
Zusammenfassung:	This invention relates to a novel application of a compound of chromium and boron, or the application of chromium boride-based coatings (e.g., CrBn where an atomic percentage of boron ranges from greater than zero atomic percent to less than 100 atomic percent of said compound) to surfaces of razor blades, namely cutting edges. On razor blade edges, these novel coatings are hard, durable, and provide a novel, low cutter force and high-quality coating structure, elevating blade performance, while also simplifying the manufacturing process.
