Abstract
Abstract NiTi alloy has good mechanical properties and biocompatibility, as well as unique shape memory properties. Therefore, it is commonly used to make metal stents in clinical practice. In this study, the substrate used is a NiTi memory alloy, which has been coated with CoNiFeP magnetic material through an electroless plating. The morphology, composition, and magnetic properties of the coating were analyzed using SEM, XRD, and VSM. The magneto-thermal properties were studied by high-frequency alternating magnetic field (AMF) induction equipment. The results showed that after determining a reasonable plating application process, the prepared coatings had certain soft magnetic properties and could exceed 43°C in a short time at different field intensities (Happl×fappl=M×109 Aꞏm−1ꞏs−1, M=1.0, 2.0, 3.0, 4.0, and 5.0) to reach the temperature required for tumor ablation, which can be used to prepare magnetic scaffolds for magnetothermal therapy.
