The evaluation of poly(limonene carbonate)s (PLCs), derived from orange oils and carbon dioxide, as UV-curable (powder) coating binders is described. PLCs with moderate molecular weight were prepared by copolymerization limonene oxide CO2 a subsequent reduction step transcarbonation 1,10-decanediol (1,10-DCD). These cured trifunctional thiol monomer in the presence photoinitiator via thiol-ene ...

Carrier particle spray freeze-drying is a new technology with high added value for thermosensitive powder freeze-drying. The includes the following steps: atomization, coating, freezing, and drying. Due to action of carrier particles, condensation frozen droplets in conventional process overcome. However, there are many influencing factors involved freezing coating. mechanism complex droplet co...

Abstract Two kinds of cermet powders, WC-10Co4Cr and WC-20CrC-7Ni, were deposited on 1040 steel via high velocity air fuel (HVAF) spraying to evaluate resistance in cavitation erosion conditions with additional electrochemical effects. Coating microstructure, phase composition, microhardness examined along the topography eroded surface layers. The WC-20CrC-7Ni coating was found be approximately...

Improving the wear resistance and corrosion of high-speed steel (HSS), WC/diamond/Co-based gradient composite coatings were produced on HSS substrates by laser cladding with different composition powder mixture (Co-Cr alloy powder, 80Co-Cr powder+20WC, 53Co-Cr powder+40WC+7diamond, wt%). The macromorphology, microstructures, phase characterized optical microscope (OM), scanning electron microsc...
