Some years ago someone here proved that all instances (except two) of adamantium being damaged in some way was retconned as secondary adamantium. Wiki says
Writers created secondary adamantium to deal with supposedly indestructible adamantium having been damaged or destroyed in the past; all such instances were retconned as appearances of secondary adamantium.
There are at least two known examples of true adamantium within the Earth-616 reality sustaining damage without molecular manipulation. The first involves the Norse god Thor focusing all of his strength into striking a small cylinder of adamantium with Mjolnir, which is only "scarcely" dented.[4] The second incident involves a battle between Ultron and the Incredible Hulk. During the fight, the Hulk punches the robot with enough force to slightly dent it.
