A. Dear Phil

Iridium electroplating is a task that an associated company in Huntsville Alabama can do. I suggest you contact Mr. Rich Edwards at Electro-Formed Nickel Inc.

I'm sure he can help you.

Sincerely

A. I heard a lecture last night at our local A.E.S.F. branch, wherein the researcher said his team did not find a commercially available iridium electroplating bath, and have not yet tried to plate it themselves. Others in the audience claimed that Lucent Technologies has developed one but that they will not license it to anyone (I don't know if this is fact or urban legend). Chris Helwig asserts in letter 3114 that his company can brush plate it.

Certainly it is possible, as pen nibs have been iridium plated and sold, and I have seen iridium plating on the contact surfaces of Japanese-made anodizing racks. Engelhard used to have a brochure on Iridium mill products but it didn't mention plating. A search through the Metal Finishing Information Service database showed a number of articles about it in the industry journals. Don't give up without contacting Technic of course.
