What's the coating for the Lander 1?

Back to Knafs.com

We've had a few people ask what the coating is on the Black Lander. It's a black titanium vacuum coating. Sound like Greek? Yeah, me too. Let's learn together from this site.

Vacuum coating, also known as thin-film deposition, is a vacuum chamber process whereby a very thin and steady layer of coating is applied to the surface of a substrate, protecting it from forces that might wear it down or decrease its efficiency. Vacuum Coatings are thin, ranging from 0.25 to 10 microns (0.01 to 0.4 thousandths of an inch) thick. What Is Vacuum Coating?

I've still got more to learn here because I'm imagining a guy in a hazmat suit blowing titanium dust out of a hose like a spray gun. More digging shows I'm not that far off, and instead of a guy, it's a machine that looks like it came from a movie. Check out this cool stuff! Granted, this isn't our manufacturer QSP doing it, but it gives you an idea of what vacuum coating looks like: Vacuum Coating Process
