Over at MR some people are saying the black iPhone 15 is DLC (diamond-like carbon), others are saying that it's a PVD (physical vapor deposition) coating, and still others are saying that the whole lineup uses PVD. However, DLC is usually produced by a PVD process (and a PVD coating could be practically any material), so the question remains-- has Apple said it was DLC or something else in particular?
I would actually prefer a titanium carbide or titanium carbonitride surface, which would make a lot more sense to me given the base metal. But either way, I'm curious.
