This DOE STTR program has produced a new technology for efficient deposition of dense boron carbide films. Such films can be used as protective coatings; they are resistant to most acids and compatible with high temperatures (over 2000{deg}C). This new technology is based on a vacuum arc discharge using boron carbide cathode as the solid feed material. This avoids the use of boron-based feedstock gases, most of which are toxic or explosive. It is superior to plasma-arc spraying, which makes low-density (porous) films and potentially more economical than magnetron sputtering, due to the low sputtering rate for boron carbide.
