I may be able to shed some light on the question at hand. First, Teflon is PTFE, or polytetrafloroethylene... that means many groups of five flrine and ethylene molecules... it's slippery plastic...
Second, those cylinder walls are probably nickel coated, not chrome plated... as in they basically take a wire of nickel and blow it up covering the walls with nickel which is extremely hard and durable. The hard chrome process is completely different from the standard copper, nickel, chrome strike process... and EXTREMELY EXPENSIVE!!! It's more complicated then reversing current. Third, Nikasil is nickel and silicon... no, not silicone!!! Nickel is extremely hard and silicon, as we all know, is even harder. Basically they are forming a metal matrix composite which is stronger then the two seperately. Even the Honda NSX has this now... Fourth, just so y'all know that I'm not shooting down ideas without helping, here is the phone to Performance coatings so that you can get your stuff coated for a reasonable price.
