Abstract：To enhance the corrosion resistance and hardness of the surface of medical device components based on ferritic stainless steel, this study employed a chemical composite plating method to prepare xCr3C2/Ni-P-PTFE (polytetrafluoroethylene) coatings on the surface of ferritic stainless steel. The influences of Cr3C2 mass concentrations (10, 15, 20 g/L) on the hardness, surface morphology, phase composition, and corrosion resistance of the Ni-P-PTFE chemical composite plating coatings before and after heat treatment were investigated. The results indicate that the incorporation of Cr3C2 particles at a certain mass concentration results in a smoother and more even surface of the Ni-P-PTFE coating, reducing surface roughness while enhancing hardness and corrosion resistance. When the Cr3C2 mass concentration is 15 g/L, the Ni-P-PTFE-Cr3C2 coating exhibits a uniform and smooth surface with the lowest roughness and a hardness (HV0.1) of 354; the surface corrosion current density decreases from 0.05 μA/cm2 to 0.02 μA/cm2, representing a 60% reduction and indicating superior corrosion resistance; after heat treatment (300 ℃, 2 h), due to the precipitation of Ni3P hard phase and Ni phase in the coating, the hardness (HV0.1) reaches 527, representing an increase of approximately 49%. The Ni-P-PTFE-Cr3C2 coating effectively improves the performance of the steel substrate used in medical device components.
