The electroless nickel with Teflon can be done fairly easily from proprietary baths. You just need to buy or license the solution.

I might be wrong, but I think the plating with electroless nickel and silicon carbide is substantially more difficult, because I believe the particles must be held in suspension (a slurry) with thixotropic agents and/or a specially designed air agitation system which makes a sort of a fluidized bed out of the solution.

Surface Technology [Trenton, NJ] has been a leader in composite nickel and electroless nickel plating for decades, and may be worth contacting.
