Evaluation of Coatings and Materials for Rotating Slitter Knives

Source

Magnetic tapes are manufactured in broad webs of large length. The single tapes are cut from this with rotating slitter knives. Because of the extremely high quality requirements to the tape edges, the endurance of the slitter knives is limited. Among other things, experiments were carried out with knives made from ceramics and cermets, with coatings of PVD-TiN, TiAlN and DLC and with ion implantation on cemented carbide knives. Most experiments were not successful, only a plasma enhanced CVD titanium nitride coating brought a technical, if not economic success.
