Professional black phosphating?
How do the professional's black phosphate machine parts?
Is it a process that could be duplicated at home. I've used the liquid blackening solutions, with limited success, the stuff simply rubs off after a short time.
I'm all ears.

G,Day Ken,
In a previous job, the company I worked for had machine parts black phosphate coated by a company in Dandenong called Black Oxide Metal Finishers, from memory they were in Patrona Street just off Princes Highway at the eastern end of Dandenong, the price at the time was about $45.00 for a 2 cubic foot bin, their turnaround time was 2-3 days, the finish was excellent and very durable.
Regards,
Martin

Pro blackening uses hot salts - not exactly something most people would do at home.
I've had success with acid fume method but it's too slow for professionals to use. It does appear to produce a more robust surface than blackening solutions.
See here.
