pics of my aluminum coated headers
Took my headers to work and coated them with aluminum. Its not as pretty as ceramic but at least they wont rust. And it was free.

What kind of headers are they?

It is a 100% pure aluminum coating. The aluminum is in a powder form and sprayed on with a plasma gun. The powder is injected into the gun which melts it and sprays the melted aluminum particles onto the sandblasted metal. There are many different types of coatings including; carbides, ceramics, graphite, moly, pure silver. If it can be melted it can be sprayed. And if it can be blasted it can be coated. I've coated a variety of different parts. Here's the technical stuff.
Plasma Spray
Plasma spray is achieved using heat transfer from a high-KW electric arc to a plasma-forming gas directed through flow enhancing nozzles. Within the spray device the gas flow chamber contains an axial stick cathode adjacent to the nozzle which forms a ring anode. In the controlled gap a DC arc is maintained through which the existing gas must pass. Heated to nominal temperatures of 10,000°F part of the gas ionizes to plasma. Ceramic or metallic powder is injected into the exit plume. It melts or is plasticized in the hot gas and propelled at high velocity to the part surface. Dilution of the plume and refined cooling techniques keep surface temperature low.

Sweet
We were looking at something on a much smaller scale the other day, used in rapid prototype machines, that uses powered metal. I think it used lasers though to heat the powder and form the part.
Either way that's awesome you have access to something like that.
