DLC coatings are notorious for application problems, and incompatibility issues. For example, at one point, Joe Gibbs racing had a large number of disastrous failures due to a particular DLC coating being incompatible with their oil. The company applying the coating changed the type of coating, and did not notify Joe Gibbs or do the requisite testing.
When DLC coating fails in any way, it is just as destructive as a Shubeck failing.
