Embodiment 1

[0025] A pure titanium sheet with a size of 10mm×10mm×1mm was mixed with acid (HF:HNO 3 :H 2 (O=1:5:4, volume ratio) after cleaning for 10 minutes, use alcohol, deionized water and ultrapure water to clean it ultrasonically, each time for 10-20 minutes, and dry it naturally for use. The plasma immersion ion implantation (PIII) technology was used to co-implant zinc and magnesium ions onto the surface of pure titanium. The titanium surface was used as a control, and zinc-magnesium-injected modified, zinc-infused modified, and magnesium-infused modified titanium metal materials were respectively obtained. Their scanning electron microscope morphology is shown in Fig. 1, and the contact angle is figure 2 shown.

Embodiment 3

[0037] A pure titanium sheet with a size of 10mm×10mm×1mm was mixed with acid (HF:HNO 3 :H 2 (O=1:5:4, volume ratio) after cleaning for 10 minutes, use alcohol, deionized water and ultrapure water to clean it ultrasonically, each time for 10-20 minutes, and dry it naturally for use. The plasma immersion ion implantation (PIII) technology was used to co-implant zinc and magnesium ions to the surface of pure titanium, and the specific process parameters are shown in Table 3. At the same time, with the same process parameters, only zinc ions and magnesium ions were implanted alone to pure titanium. The titanium surface was used as a control, and zinc-magnesium-injected modified, zinc-infused modified, and magnesium-infused modified titanium metal materials were respectively obtained.

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...
