Tirumalai,
it is entirely possible.Generally trivalent black passivation is followed by a top coat.After top coat components have a look like it is painted.
contact any supply house in and around your city.There are many.
good luck

Dear Mr Shanmugam,

It may be painted after all, the finish you are looking at is probably CED Coated.
