Im making some SS and carbon steel products. the carbon steel products need to be coated (grey or black) and then fiber laser engraved for data.
is there any way to get a nice engraving that does not destroy the coating and then rust? ive been hot phosphating them but the customer now wants engraving.
i can deep engrave and then phosphate, but a opposing color/sharp image would be prefered. im just not seeing a solution in my head.
for the SS, whats a good way to blacken? (preferably something that can be done on a small/cheapish scale, $5000 and under initial setup for small handheld parts)
i considered sandblasting/laser engraving to a nice black with the graphics remaining the sangblasted SS but the laser polishes the steel as it blackens (surface aneeals is) i want the matte effect of sandblasting to remain (more laser testing to go. maybe its acheavable but i doubt it
i often laser engrave anodized aluminum products and boy, what a nice result, the laser bleaches the dye and the coating is left, stunning white results.
