Example Embodiment

[0024] Example 1

[0025] The pure titanium sheet with a size of 10mm×10mm×1mm is mixed with acid (HF: HNO 3 :H 2 O=1:5:4, volume ratio) After cleaning for 10 minutes, ultrasonically clean with alcohol, deionized water and ultrapure water in sequence, cleaning for 10-20 minutes each time, and dry naturally for later use. Plasma immersion ion implantation (PIII) technology is used to co-implant zinc and magnesium ions onto the surface of pure titanium. The specific process parameters are shown in Table 1. At the same time, only zinc ions and only magnesium ions are injected separately to pure titanium with the same process parameters. The titanium surface was used as a control to obtain titanium metal materials modified by zinc and magnesium injection, zinc injection and magnesium injection. Their scanning electron microscope morphology is shown in Figure 1, and the contact angle is as figure 2 Shown.

Abstract

The invention discloses a titanium metal material surface modifying method and a modified titanium metal material obtained through the method. The method is characterized in that zinc ions and magnesium ions are co-implanted to the surface of a titanium metal material through a plasma immersion ion implantation technology in order to improve the biological activity of the medical titanium metal material. The modified titanium metal material has the characteristics of improved corrosion resistance, good cell spreading performance and increased cell proliferation rate, can promote ossification differentiation of rBMSCs, and has an ossification promotion effect.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a method for modifying the surface of a titanium metal material and the obtained modified titanium metal material. Background technique [0002] Surface modification (Surface modification) refers to a technology that treats the surface of a material to change its properties, such as carburizing (or nitriding), shot peening, laser treatment, ion implantation, surface coating, anode Oxidation, Chemical Vapor Deposition, Physical Vapor Deposition, etc. Among them, plasma immersion ion implantation (PIII) technology is a new, cheap, non-line-of-sight surface modification technology developed in recent years. The technology is to directly immerse the workpiece to be implanted in the plasma, and apply a series of negative potential pulses on the workpiece relative to the wall of the vacuum chamber. At this time, a continuously expanding / retracting plasma sheath i...
