Electrodeposition of cermets
Modern engineering requirements are frequently near the limits of application of conventional materials. For many purposes, particularly tribological, the most satisfactory solution is frequently the application of a resistant coating to the surface of a common metal. Electrodeposited cermet …

The edge flaking of tungsten carbide hardmetal cermets under repetitive impact loading
… performance of several grades of hardmetal cermets. In an attempt to understand the geometry and characteristics of the crack propagation glass was impacted. Various types of cracking are observed in the glass including crushing, lateral cracking, median cracking and Hertzian cone cracking. …

Investigation of erosion-corrosion behaviour of pump materials
… alloys. Sintered and HVOF coatings WC-based cermets of similar chemical composition were studied to elucidate the influence of the manufacturing process on their erosion-corrosion response of the cermets. The manufacturing process effect resulted to be significant as the sintered cermets …

Erosion-corrosion resistance of tungsten carbide hard metals with different binder compositions
… between the performance of the Ni-Cr-Co based cermets and the pure alloyed metal binder grades. The acceptability of modelling the slurry erosion and corrosion resistance of cermets based on the behaviour of the binder phase materials is discussed.

The wear of materials in an ash conditioner
… selection, a family of tungsten carbide-cobalt cermets together with a number of structural ceramics were tested in situ. The modes of wear can be related to material constitution. By ranking the performance of these candidate materials, value based materials selection and design for use can be …

Fabrication and characterisation of nickel/yttria stabilised zirconia cermet anodes for solid oxide fuel cells
… cermet anodes to coarse structure cermets to two-dimensional Ni anodes with significantly higher polarization resistance. The anode structure-dependent high frequency section of the impedance spectrum was studied. The thesis concludes with recommendations for further investigations.

Growth and characterisation of multifunctional nanocomposite coatings
Novel nanocomposite coatings of the type Fe-Ti-N and Fe-Ti-O-N, having in-situ formed periodic multiphase nanocolumnar microstructures, have been developed by a two-target reactive magnetron sputter deposition and nanoparticle-assisted electro-co-deposition processes. Advanced thin-film …

Erosion-Corrosion of Cr3C2-NiCr High Velocity Thermal Spray Coatings
… response of thermal spray coatings and bulk cermets is more widely understood, most works have been conducted under milder conditions than used in the current work. In addition previous works have been conducted primarily on assprayed coatings with few works taking into account the effect of …
