CVD diamond coatings on geometrically complex cutting tools
The manufacturing of chemical vapour deposition (CVD) diamond coated shaft type cutting tools is demanding due to the complex design of the cutting edges and the cobalt content of the cemented carbide. The influencing parameters of substrate, pre-treatment and diamond film on the tool cutting performance are discussed. The optimised manufacturing route of CVD diamond coated thread milling drill...
متن کاملTiAIN based nanoscale multilayer coatings designed to adapt their tribological properties at elevated temperatures
The addition of properly selected elements, coupled in nanoscale multilayer structures can further enhance the properties of TiAlN coatings and bring new high performance. The incorporation of Y in the nanoscale pseudo-superlattice TiAlCrN/TiAlYN with typical period of 1.7 nm not only improves the oxidation resistance but also effectively reduces the coefficient of friction of the coating from ...
متن کاملHigh temperature tribological performance of CrAlYN/CrN nanoscale multilayer coatings deposited on γ-TiAl
Nanoscale multilayer nitride coatings deposited by advanced PVD techniques have shown particular promise in improving the tribological properties of a number of modal alloy steels [1]. In this study, we report the effect of temperature on the friction and wear behaviour of a CrAlYN/CrN multilayer coating with a CrAlYON/CrON topcoat deposited on γ-TiAl. Deposition was performed by unbalanced mag...
متن کاملIon-assisted CVD of graded diamond like carbon (DLC) based coatings
Graded DLC based coatings and multilayers for wear resistance applications have been produced using a novel hybrid unbalanced magnetron sputtering1 low pressure CVD system. The main features of this highly flexible and scalable process are discussed. These films have been characterised using a variety of techniques including SEM, microhardness, adhesion, wear rate and lifetime tests. For exampl...
