Abstract The in-situ formation of oxides on alloy surface induced by high temperature can effectively reduce wear and resist oxidation. In consideration the solid solution strengthening effect great oxidation resistance additional elements at elevated temperature, NiCrWMoCuCBFe coating was prepared velocity oxygen flame (HVOF) spraying technology, its tribological behavior scrutinized from 25 t...

Reference ice accretion experiments are reproduced numerically using the simulation framework PoliMIce to investigate solid blockage effects and wall-model boundary layer interaction at the wall-model juncture. The open-source OpenFOAM software is applied to the computation of the aerodynamic flow-field and of the trajectories of water droplets. The thickness of the iced layer is then determine...

The production of confectionery products, especially those coated with chocolate or glaze, faces the challenges selecting high-quality and technological fatty bases for glaze filling on a daily basis. In nature, amount vegetable oils that have an optimal acid triglyceride composition use as such base is significantly limited. Indeed, most fats require partial hydrogenation stage, is, change in ...
