Zusammenfassung:The TiAlN/AlCrN coating film deposited by AIP (Arc Ion Plating) is applied to the end mills and some types of such tools are used in dry milling of SUS304. The structure of TiAlN/AlCrN consists of a TiAlN layer and AlCrN layer. This coating film was designed to improve mechanical properties. The scratch test revealed that the exfoliation load of TiAlN/AlCrN film is higher than a monolayer of AlCrN, and has high adhesion with base material. On heating test of coating films, the TiAlN/AlCrN film shows high hardness of 20 GPa or more after heating to 1000 degree C. This temperature is 200 degree C higher than that of TiAlN coating film. Long tool life is obtained with these TiAlN/AlCrN-coated tools compared to ordinary TiAlN-coated tools and AlCrN-coated tools.
