This is a somewhat specific question to which I don´t know the answer. Possibly the following reference is pertinent (though it refers to DLC containing silicon).

DLC means Diamond-Like Carbon, a kind of thin film materials, which can be coated on metals for preventing corrosion and wear damage.
Then that is not my field of research. I do metal nanocluster deposition on various substrates.

Generally, DLCs can be useful for corrosion inhibition, but since the term DLC pertains to a rather wide range of materials (e.g. a-C:H, ta-C:H. a-C, ta-C, a-C:ME, etc..), it's difficult to give a specific answer.
One of the most important points to consider when developing protective DLC coatings is that these can have an inherent tendency towards porosity (although there are ways of circumventing the problem). A porous coating can actually accelerate corrosion when compared to the uncoated substrate!
