Laser Marking Steel
sparky961:
Did you test the durability of the marking at all? Maybe take some steel wool or similar to it? I'm curious how much this is etching vs. just converting something in the spray to carbon.

Its pretty good. You can sand it off, but it takes quite a lot of work and you can still see the mark on the bare metal. I'll go over half that test piece with some scotch bright tomorrow and post a pic.
The CerMark stuff is well and truly good enough for our applications (industrial electronic enclosures, and sensors). We use it on 316 stainless, nickle plated steel, and anodised aluminium. Many of the items operate outside and the marking is good after years of weathering.

I used to program and run multi-kW industrial lasers at a job a couple of years ago. With both CO2 and diode/fibre machines, we'd just "etch" at a low power setting, and usually just outlines rather than fills. The results were usually quite nice in terms of resolution and consistency but the contrast was always poor. I wish I'd have known about this while I was still there, as I'd have a ton of things around here still that were laser marked. :)

So here's the abrasion test. I used some OOO steel wool and scrubbed as hard as I could for a minute or so.
All the tests Held up about the same and pretty well I reckon.

That's pretty impressive.
