This article was published on "CompositesWorld," July 13th, 2021. The article details the results of a seven-month project that detailed the ability to withstand up to 3,500°C and it showed promising initial results.
• Density: VC has a higher density (5.77 gm/cc). VC/C is light-weight 2.5 to 4 gm/cc with carbon core: VC conversion layer is near diamond hardness • High-temperature material (2730 C melt) • Key feature: VC is wettable by iron and steel in alloys. VC nano used in grain boundary refinement steels.
• Normally very dense (14.3 g/cm3) but lighter with a carbon core • High-temperature material (3880 C vaporizes) • Near diamond hardness
• HFC layer is near diamond hardness • High-temperature material (3900 C melt) • Density: VC has a higher density (12.2 gm/cc). TaC/C is light-weight 2.5 to 4 gm/cc with carbon core • Key feature: High-temperature stability. Forms mixture with TaC
• Wettable by aluminum (possible reinforcing material) • Near diamond hardness • High temperature (3065 C melt) • Low density (4.94 g/cm3) • Inexpensive metals source
• Low density (3.16 g/cm3) • High-temperature material (2830 C vaporizes) • Near diamond hardness • Can have either conductive or insulative electrical properties
