Effect of high-voltage pulse bias on the stress and morphology of CA-PVD TiN coatings [PDF]

, 2020
We investigated the role of high-voltage pulse bias (HVPB) on the structure, morphology and residual stress of TiN coatings produced with cathodic arc physical vapour deposition and compared them with the ones produced with DC bias.
