From memory Steve, too durable for wet paint, too thin for powder, so I would say some kind of electro plating.

if you are refering to the black finish as on ashtabula parts and spindles on pedals,  then its chemical blacking,  theres a local guy to me that does this type of work along with zinc coatings on all my crusty old nuts and bolts....   ;)
