Designs and preparation of advanced HVOF-PVD duplex coating by combination of HVOF and arc ion plating [PDF]
Surface and Coatings Technology, 2016 Abstract Advanced HVOF-PVD duplex coatings were produced on the medium carbon steel by combinations of High Velocity Oxygen-Fuel (HVOF) and arc ion plating. The microstructures and mechanical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) in association with mechanical property measurement.

Numerical modelling the bonding mechanism of HVOF sprayed particles [PDF]
Computational Materials Science, 2009 During high velocity oxy-fuel (HVOF) thermal spraying, most powder particles remain in solid state prior to the formation of coating. A finite element (FE) model is developed to study the impact of thermally sprayed solid particles on substrates and to ...

Keraamipinnoitteiden valmistus HVOF-ruiskutuksella
, 2000 Keraamien pinnoittaminen termisesti ruiskuttamalla suoritetaan yleisesti plasmaruiskutuksella. Keraamien pinnoittaminen HVOF-ruiskutuksella (suurnopeusliekkiruiskutuksella) on poikkeuksellista.

Development of Nanostructured Al2O3- Ni HVOF coatings
Key Engineering Materials, 2006 HVOF thermal spraying has been developed to deposit dense Al2O3-coatings for improved protective properties. As compared to generally used plasma sprayed coatings HVOF coatings can be prepared much denser and thus are better suited for applications where
