The hardness and post-scratch surface morphology of Cr₃C₂–NiCr coatings subjected to ultrasonic nanocrystal surface modification (UNSM) were examined for detonation-sprayed (DS) and high-velocity oxy-fuel (HVOF) deposits. Four treated samples per deposition route were evaluated at static loads of 20 and 30 N and vibrat...

This study investigates the effect of a static contact load applied during ultrasonic nanocrystal surface modification (UNSM) on WC-12Co coatings deposited by detonation spraying. Surface roughness, surface and cross-sectional microstructure, mechanical properties, and adhesion–cohesion strength were evaluated using co...

The effect of Ultrasonic Nanocrystal Surface Modification (UNSM) on the structural, mechanical, and tribological properties of WC–12Co coatings deposited by high-velocity oxygen fuel (HVOF) spraying onto 12 × 18H10T steel was investigated. The coatings were treated with UNSM using four combinations of amplitude (20 and...

Thermal barrier coatings protect metallic components operating under severe high-temperature conditions, but conventional yttria-stabilized zirconia (YSZ) coatings face limitations at elevated temperatures. Gadolinium zirconate (Gd2Zr2O7, GZO) is a promising alternative topcoat material; however, controlling its porosi...
