[SRAM] chainring surface flaking

[beardedwarbler]

Morning,

I'm upping my mileage slightly and my chain is attracting the dreaded black gunk after a short number of miles, even with fair weather and - I would personally say - fairly light application of lube, with excess thoroughly wiped off.

On cleaning, it looks like the chainring is generating a lot of it - the ring's teeth were black, but the coating has clearly come off. Chain, rings and cassette are all fairly new. I can't imagine the coating would stand up to any significant usage.

Anyone else experienced this? I'm guessing there's not much for it, just wait?

Always though SRAM stuff was a bit flaky

The "coating", that is, the hardened surface / case depth, of the aluminium?

Squirt lube in the summer months = no black gunk.

I remember, years ago, cleaned the rims thoroughly, replaced brake pads, and my rims were coated with black grit just a couple days later, no rain, no mud, no dust. Apparently, the new brake pads had a kinda surface material that was scraped off quickly.

Breaking it down as I read it (and its my interpretation so I may be wrong)
Excess oil on the chainring particually. What oil are you using ? If its light and fluid, its just a fact of life, the dust, debris, metal particles that gets chucked out a chain is dirty and black. Do you heavily oil your chain ? Personally, I only drop a little drop on each roller, no more and I still get dirty chainrings. Only consolation is its a quick wipe to get it clean again.
Flaky chainrings ? Plating sounds as though its coming off. Maybe a failure in the manufacturing process but I wouldn't have thought its anything serious, just a cosmetic thing.
