In this study, molochite (calcined kaolin) and dolomite with particle sizes (ca.1 mm) similar to those of the sand bed materials industrial-scale fluidised beds, rather than powders which were normally used by previous studies, investigated as additives counter agglomeration combustion wheat straw miscanthus pellets in a 20 kW th bubbling combustor under both conventional air oxy-fuel condition...

Thermal spray has traditionally been used for depositing metallic, carbide and ceramic coatings, however, it has recently been found that the high kinetic energy of the High Velocity Oxy-Fuel (HVOF) thermal spray process also enables the solventless processing of high melt viscosity polymers, eliminating the need for harmful, volatile organic solvents. A primarily goal of this work was to devel...

Abstract In this work, the tungsten carbide reinforcement in cobalt matrix (WC-Co-Cr) coatings was studied. The deposition process carried out by high-velocity oxy-fuel spraying (HVOF). study aimed to investigate influence of one key parameters, namely spray distance, on coatings’ microstructure and phase composition, as well their mechanical tribological properties. manufactured were analysed ...
