Tape Adhesion Test

A coating adhesion test where a specific certified tape is applied to the coated part and then removed. Any loose coating that comes off with the tape is cause for rejection. In general, this test is not adequate for testing PVD coatings because the tape adhesive force is much lower than the coating adhesion. However, it is a reasonable assurance that the adhesion is not terrible. If any coating comes off on the tape, it is a sign of a serious adhesion problem in the PVD film.
