Article Synopsis
- The controversy surrounding how cavitation heat impacts material surfaces complicates the understanding of cavitation erosion (CE) mechanisms and hinders the creation of protective materials.
- An innovative anti-cavitation erosion coating made from an AlCrCoNi high-entropy alloy was developed using high-velocity oxy-fuel (HVOF) spraying, focusing on balancing mechanical and thermal energies.
- Experimental results revealed that while the coating refined its grain structure and increased dislocation density under cavitation stress, it also showed that cavitation heat caused grain growth and structural changes, leading to enhanced resistance to cavitation erosion, outperforming classical coatings significantly.
Hydroxyapatite (HA) bioceramic coating has been extensively applied for the modification of metallic implants to improve their biocompatibility and service life after implantation. Unfortunately, HA coating often suffers from high friction, severe wear, and bacterial invasion, which restrict its application in artificial joints. According to a bioinspired soft/hard combination strategy, a novel HA composite coating that is infiltrated with a vancomycin-loaded graphene oxide (GO) hybrid supramolecular hydrogel is developed vacuum infiltration and a subsequent host-guest interaction-induced self-assembly process.
