Embodiment

[0040] 1. Use the above-mentioned treatment steps to carry out surface treatment on the implant, and the specific treatment process parameters are shown in Table 1 and Table 2 below.

[0041] The processing parameters of each group in table 1

[0042]

[0043]

[0044] The processing parameters of each group in table 2

[0045]

[0046]2. The implants treated according to the process parameters disclosed in Table 1 and Table 2 are tested for water drop angle. The test starts when the implant treatment is completed, and after 10 days, 20 days and 30 days respectively, the water drop angle test is performed again , the test results are shown in Table 3 below. The smaller the water drop angle test value on the implant surface, the stronger the hydrophilicity. Therefore, the results in Table 3 below show that the water droplets are almost flat on the surface of the implant after hydrophilic treatment, and the results of the water drop angle test are between 1° and 4°, w...

Abstract

The invention relates to the technical field of metal surface treatment, in particular to a treatment process for hydrophilic implants. The specific technical scheme is: a treatment process for hydrophilic implants, which involves treating the implants after sandblasting and acid etching with alkaline solution and acid solution in sequence, and then vacuum calcining the treated implants. The invention solves the problem of long healing time after implantation due to poor hydrophilicity of the implant in the prior art.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a treatment process for hydrophilic implants. Background technique [0002] Hydrophilic implants contain hydrophilic groups on the surface, which can quickly combine with water molecules in body fluids. Plasma proteins, platelets, calcium ions and other water molecules in blood and body fluids are deposited on the surface of implants together with water molecules, thereby forming a large number of apatite. Apatite is the main component of bone cells. The introduction of hydrophilic groups shortens the time for osteoblasts to adsorb and divide and grow, and also greatly improves the survival probability of implants. [0003] At present, most of the implants on the market are ordinary hydrophobic products, and the surface treatment process is mostly sandblasting and acid etching. Due to the strong oxidation of concentrated sulfuric acid during the acid etching proc...
