Microstructure and Properties of Cu-Ni20Cr4B Antifouling Coating Prepared by Atmospheric Plasma Spraying

doi:10.3901/JME.2025.10.090

Abstract

Abstract: The low adhesion strength and hardness of makes polymer antifouling coatings easily spalled-off when the coating served in high-flow sea water containing sand grits. In the present work, Cu-Ni20Cr4B composite coatings are prepared by atmospheric plasma spray(APS) with mechanically mixed Cu-Ni20Cr4B feedstock powders. Antifouling is attempted to be realized by the galvanic interaction between Cu and Ni20Cr4B splats in seawater which releases Cu²⁺continuously. Effect of the Cu to Ni20Cr4B ratio on microstructure, mechanical properties and antifouling performance is investigated. Results show that the porosity and oxide content of the composite coating decreases with the increase of Ni20Cr4B, significantly lower than those of APS conventional metal coatings. The bonding strength and quartz sand slurry wear resistance of the composite coating increases with the increase of Ni20Cr4B in the coating. The bonding strength of the composite coating with Cu to Ni20Cr4B volume ratio of 1∶2 reaches 54.2 MPa, and the quartz sand slurry wear resistance is about 16 times that of commercial acrylic antfouling coatings. The Cu-Ni20Cr4B composite coating can stably release Cu²⁺ and exhibit excellent antibacterial properties. Compared with TC4 titanium alloy, the antibacterial rate can reach over 99.3%. The results of the actual sea hanging test show that the Cu-Ni20Cr4B coating exhibits excellent anti marine biological adhesion performance.

Key words: marine fouling, atmospheric plasma spraying, Cu-Ni20Cr4B composite coating
