Teflon (or generically fluoropolymer or non-stick) coatings have an
appeal for certain jobs (like the inside of snowblowers and lawnmowers)
where manufacturers have chosen not to put them. I've always assumed
that the process is beyond small-shop capabilities, and gone in with
paint and wax when the rust and sticking of stuff that should slide out
is too bad. Is there some system that could work in a small shop, and is
accessible to mere humans without DuPont licenses and/or giant
heat-treating ovens?

Or particular (easily available) paints that do a better job of
approximating the effect, without being members of that family...?

For the mower, if you have room, screw some 1/4 " UHMW in the wear
areas. Besides being pretty slick, it is VERY resistant to abrasion.
It has to be mechanically fixed in place, with bolts and plates or
deeply countersunk holes, etc. But it will last longer than the mower
deck above it. I know this really doesn't help with the coating
problem the way you hope to solve it but teflon isn't durable enough
for your application. Even teflon sheet would not work well for this.
It's too soft and would just be pulled off the bolts.
