Zeref's black magic was burned away/combatted by Natsu's flames, the same flames that got easily frozen by Invel. It still took some time for Natsu to unfreeze himself and Invel could have killed him during that time. Ice Lock worked on Mavis who although not strong factually has among the highest amounts of magic power contained in her body. Hence,I don't see why it wouldn't work on Zeref or even Natsu without friendship bs. Plus he doesn't even need to move to freeze things so I doubt that Zeref's black flame death magic would be much a problem
