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

The interface of ARMCO iron during electrochemical machining (ECM) was investigated by microelectrochemical techniques. The results lead to a duplex layer structure model, a solid oxide film, and a supersaturated viscous layer. The consequences on pu

The high field model had to be modified for the anodic growth of amorphous oxide films (Al, Nb, and Ta). Mobile ions are only formed at the interfaces and migrate through the film. Simulations based on this assumption show a very similar shape of cur

The initial step of anodic growth of thin oxide films (1 to 100 nm) on Al and Ta is the simultaneous emission of metal cations from the interface metal/oxide and oxygen ions from the interface oxide/electrolyte. These ions represent mobile space char

This presentation recalls the peculiarities of anodic polarization valve metals namely aluminium and Tantalum. Both metals are very unnoble and react immediately with oxygen or water. They form an anodic oxide that hinders further transport of anions

The reversible redox process of electrochemically formed conducting polymers (poly-aniline, poly-3-methylthiophene, poly-carbazole, and poly-bithiophene) was investigated by current transients of potentiostatic steps, impedance spectroscopy, and by m
