Dermal exposure to sensitizing metals is a serious occupational and public health problem. The usual approach to dermal exposure assessment is to process samples by chemical methods that use reactants to digest the metal particles and quantify the mass. In the case of dermal exposure assessment, these reactants are not representative of the skin surface film liquids and hence, may overestimate ...

The ability to axially inject liquid feedstock has encouraged the thermal spray research community explore this concept deposit coatings for various next generation functional applications. current study explores utilization of in high velocity air fuel (HVAF) spraying solid lubricant reinforced wear resistant first time. successfully demonstrates use a powder-suspension hybrid processing appro...

Physicochemical patterns of complex reduction multicomponent charge have been studied in the absence liquid phases order to obtain spongy ligatures. The contained both simple oxides and oxide compounds. was conducted being realized at expense carbon gases (CO H2) as well with participation carbide phase, which formed during process. dependence phase composition products on initial ratios O/(C+H...

Abstract Thermal barrier coating plays a vital role in protecting materials’ surfaces from high-temperature environment conditions. This work compares the demeanour of uncoated and air plasma sprayed Cr 3 C 2 –25NiCr NiCrMoNb coated X8CrNiMoVNb16–13 substrates subjected to oxidation molten salt (Na SO 4 + 60%V O 5 ) condition at 900 °C for 50 cycles. Coating characteristics have been analyzed t...

Additive manufacturing by laser-based powder bed fusion of metals (PBF-LB/M) enables the production complex shaped components. High-carbon tool steels tend to cracking during PBF-LB/M due internal stresses caused rapid solidification. Expensive atomization and long lead times for generate high costs in this processing route. In situ alloying blends from conventionally available powders a more f...

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...
