Keystone Steel & Wire in Peoria IL does some Sherardizing. The process consists of tumbling small parts with sand, flux, and zinc dust and heating it until the zinc fuses to the surface of the part, followed by a quench.

Sherardizing is a method of batch galvanizing. It is ideal for small parts and parts that require coating of inner surfaces, although, there are systems that can do pipes as long as 12', and rail guards. The original system was quite complicated and expensive; however, today there are new systems in use which are simple, cost effective, and environmentally friendly. As far as corrosion protection, I don't know about the old systems, but the one I am familiar with is showing far superior results then any other systems I'm familiar with. Another advantage of this system is that it allows easy application of top-coats and paints.
For more information on sherardizing you can check BS EN 13811 [link is to spec at TechStreet]::2003 (this is the British/European Union standard).
