I've got a person that wants me to engrave a logo into a 6061 aluminum part that they will then get show chrome plated. Anybody know how deep or high depending on whether I emboss/deboss the logo it needs to be so the chrome doesn't fill it in? Any general parameters to take into consideration?

Crome is very thin to the point that even grinding marks left in the base part will show up if they don't prep it right
I would say .005 to .010 should suffice however I think that would depend on the logo

We restore many ash trays and other delicate chrome parts for Ferraris. When doing any kind of engraving work with chrome, we have the part copper plated and polished first. It brings out much better detail in the artwork once chromed. The chrome and nickle are extremely thin, however the copper plating is usually built up some so it can be polished.
Thanks, the other thing mentioned was they want to paint fill the engraved areas after chromed. I'm guessing auto enamel? One article I found said 60% enamel mixed with 40% thinner and then use a syringe to fill the areas in.
We do alot of that as well. As far as paint goes, a quality single stage (usually Chroma One by DuPont) is what we use, thinned as needed. An enamel should do good also, depending on conditions the part is exposed to. If its just a single line engrave, i've found that using a piece of mechanics wire to lay the paint will save alot of time in cleaning up edges. If its a pocket engrave, the syringe should work well.
