Powders of copper and aluminium with a maximum grain size of 50 µm are mixed in different ratios. The mixtures are cold isostatically pressed into two‐inch circular targets which are mounted in a conventional magnetron set‐up and used to deposit both metallic Cu–Al as well as oxygen rich Cu–Al–O thin films. In both cases the thin film composition is analysed and related to the target composition....
Laser cladded coatings consisting of various types of tungsten carbides embedded in a NiCrBSiCFe matrix are characterized. At optimal process parameters crack-free coatings with a thickness of 0.85-1 mm, excellent bonding with the substrate, carbide concentrations up to 60 wt% and a hardness in the range of 40–55 HRC are obtained. During laser cladding the carbides have partly dissolved in the matrix...
