Abstract
A high-temperature component of a refractory metal or a refractory metal alloy has an emissivity-increasing coating. The coating is formed of tantalum nitride and/or zirconium nitride; and tungsten with a tungsten content between 0 and 98 wt. %.
Claims16
A high-temperature component, comprising:
- a component body of refractory metal or a refractory metal alloy;
- an emissivity-increasing coating on said component body, said coating consisting essentially of:
- at least one nitride selected from the group consisting of tantalum nitride and zirconium nitride, and tungsten with a tungsten content of more than 0 wt. % and up to 98 wt. %;
- and
- wherein said coating is a sintered composite layer of tantalum nitride particles and/or zirconium nitride particles, and tungsten particles.
