High-temperature resistant coatings
Thread Content
I am looking for a high-temperature resistant coating suitable for use on metal surfaces with low roughness, one that can function over extended periods in an environment of 800 degrees Celsius. The thickness of the coating should be within 10 micrometers, and the substrates are pure tungsten and pure molybdenum. . Those who are familiar with such products please recommend them; manufacturers with such products are also welcome to introduce themselves.
With this temperature and thickness, forget about applying a coating; it’s better to use refractory materials or metal instead
How are refractory materials bonded to tungsten substrates?
