Bei Zahnradpaarungen, die langere Zeit beansprucht sind, entstehen an den Flanken haufig Risse. Deren Verteilung und deren Ausrichtung zur Flankenoberflache lassen sich aus der Kinematik des Abrollens erklaren. Die Risse bilden zur Oberflache einen W

Although magnesium alloys became popular in the first half of the 20th century, the bad corrosion properties prevented their breakthrough in industrial mass production. Since the technology for the production of high purity alloys was introduced in t

Amorphous silicon carbon nitride (Si/C/N) coatings were prepared on steel substrates by RF plasma-enhanced chemical vapour deposition (RF-PECVD) from the single-source precursor bis(trimethylsilyl)carbodiimide (BTSC). The films were characterised by

The present study investigates the potentials of newly developed (Cr,Al)N coatings compared to uncoated tools. The aim of using chromium-based coatings is to create a thermal barrier and thus redirecting the heat from work piece and tool into the chi

Amorphous Si/C/N:H where synthesized by plasma enhanced chemical vapor deposition (PE-CVD) using the single-source precursors hexamethyldisilazane (HMDS) and bis(trimethylsilyl)carbodiimide (BTSC). The films produced using the HMDS precursor were ric

Different types of PVD coatings and plasma treatments were applied for the surface treatment of magnesium die cast alloy AZ91 specimens. The different types of surface treatment were all developed by the authors and the fundamental properties are des

The PVD plasma anodisation method developed by the authors allows the anodisation and subsequent PVD deposition of magnesium alloys in a process step using a conventional PVD sputtering unit. In the standard salt spray test, these surfaces show corro

Tools for cutting operation are subject to very high abrasive, adhesive, and thermal loads. Process security and preparation quality as well as a sufficiently high tool life demand for the development of hard coatings with reduced seizure tendency, h

Developing PVD coating systems with better corrosion resistance leads to a duplex process, consisting of a plasma anodisation and an Al 2 O 3 top coating which can both be performed in a modified commercial PVD unit. The tested specimens were investi
