Assessment of microstructure and tribological performance of ZrO2-reinforced MAO coatings on 7075 aluminum alloy using grey relational analysis

Effects of Deposition Parameters on the Microstructural Evolution and Mechanical Properties of TiN Coatings on 7075-T6 Aluminum Alloy

The 7075-T6 aluminum alloy exhibits excellent specific strength due to the presence of precipitated η′ phase, but its surface mechanical performance under demanding conditions is often limited. In this study, a horizontal cylindrical magnetron sputtering system was used to deposit TiN coatings on the surface of 7075-T6...

Investigation on mechanical and tribological properties of AZ61/10 wt% ZrN composites prepared by stir casting method

Microstructure and Properties of Aluminizing Coatings on 0Cr21Al6Nb Stainless Steel Prepared by Pack Cementation

Fe-Al intermetallic coatings were fabricated on 0Cr21Al6Nb stainless steel by pack cementation to systematically investigate the effects of temperature (650–800 °C) and holding time (2–16 h) on the coating microstructure, phase constitution, and hardness. The coatings primarily consisted of Fe2Al5, with a minor amount...

Microstructure and tribological behavior of a bilayer AlCoCrFeNi/Y₂O₃ high-entropy alloy coating fabricated via extremely high-speed laser cladding

Effect of Al₂O₃ Addition on the Surface Roughness, Adhesion Strength, and Microstructure of Flame-Sprayed Cu–Al–Ni–Fe Alloy Coatings

This study aims to synthesize (Cu-Al-Ni-Fe) alloy composite coatings reinforced with alumina (Al2O3) particles at weight fractions of 0 wt%, 3 wt %, and 6 wt%, deposited on AISI 304L stainless steel substrates using the flame thermal spraying technique. The coatings were evaluated by measuring surface roughness and adh...

Microstructure and Corrosion Resistance of Ni-Based Laser-Cladded Coatings Reinforced with ZrC on Structural Steel

To mitigate the poor corrosion resistance of 45 steel components, ZrC-reinforced Ni-based composite coatings were fabricated on 45 steel substrates via laser cladding. The phase composition and microstructure were systematically characterized by XRD, FE-SEM, TEM, and EBSD, and the corrosion performance was evaluated by...
