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...
