PY - 2012 DA - 2012/12/19 TI - Mechanical and Tribological Properties of PVD-Coated Cemented Carbide as Evaluated by a New Multipass Scratch-Testing Method SP - 305209 VL - 2012 AB - A new test method based on multipass scratch testing has been developed for evaluating the mechanical and tribological properties of thin, hard coatings. The proposed test method uses a pin-on-disc tribometer and during testing a Rockwell C diamond stylus is used as the “pin” and loaded against the rotating coated sample. The influence of normal load on the number of cycles to coating damage is investigated and the resulting coating damage mechanisms are evaluated by posttest scanning electron microscopy. The present study presents the test method by evaluating the performance of Ti_0.86硅_0.14N，钛_0.34人_0.66N，和（铝_0.7铬_0.3）₂Ø₃通过在的硬质合金刀片阴极电弧蒸发来沉积涂层。结果表明，试验方法是快速，简便，且可再现的，并且可以优选地使用，以获得关于疲劳，磨损，缺损，和剥落不同涂层 - 底物复合物的特性相关的数据。该测试方法可以用作几乎无损检测，并且，例如，被用来评估疲劳和耐磨损性以及前切削试验涂覆的硬质合金刀片的内聚和粘合界面强度。SN - 1687-5915 UR - https://doi.org/10.1155/2012/305209 DO - 10.1155 /三十○万五千二百〇九分之二千〇一十二JF - 摩擦学PB进展 - Hindawi出版公司公司KW - ER -
