specific Embodiment approach 1

[0032] Specific Embodiment 1: This embodiment is a method for preparing an up-conversion fluorescent developing coating on the surface of a magnesium alloy, which is completed in the following steps:

[0033] 1. Magnesium alloy pretreatment: Use 180#SiC sandpaper, 1000#SiC sandpaper and 2000#SiC sandpaper to polish the magnesium alloy in sequence to obtain a bright magnesium alloy;

[0034] 2. Ultrasonic degreasing: immerse the bright magnesium alloy in acetone, and then ultrasonically treat it for 5min-10min at an ultrasonic power of 800W-1000W to obtain the magnesium alloy after ultrasonic treatment; rinse the magnesium alloy after ultrasonic treatment with distilled water 3 to 5 times, and then use a hair dryer to dry to obtain a degreased magnesium alloy;

[0035]3. Preparation of rare earth hydroxyapatite precursor: mix hydroxyapatite, erbium oxide and ytterbium oxide, and then grind for 2h to 4h to obtain a mixed powder; calcinate the mixed powder at a temperature of 750...

specific Embodiment approach 2

[0056] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the particle size of the hydroxyapatite in step 3 is 40nm-900nm. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0057] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the power of the ultrasonic dispersion described in Step 3 is 800W-1000W. Other steps are the same as those in Embodiment 1 or 2.

Abstract

A method for preparing an up-converting phosphor developing coating on the surface of magnesium alloy is disclosed and relates to a method of preparing a phosphor developing coating. The object of thepresent invention is to solve the problems that the biological activity and X-ray development performance of existing magnesium alloy are relatively poor, and the magnesium alloy is restricted as a medical implant material. The method comprises the steps of 1, magnesium alloy pretreatment; 2, ultrasonic de-oiling; 3, preparation of a rare earth hydroxyapatite precursor;4, preparation of an electrolyte; and 5, micro-arc oxidation. Therefore, the up-converting phosphor developing coating is prepared on the surface of magnesium alloy. After the surface of the magnesium alloy is enhanced by the method of the invention, the up-converting phosphor developing coating is obtained on the surface of the magnesium alloy, and the bonding strength of the up-converting phosphor developing coating and the matrix magnesium alloy can reach 80 MPa. Through the present invention, the up-converting phosphor developing coating can be obtained.

Description

technical field [0001] The invention relates to a method for preparing a fluorescent developing coating. Background technique [0002] Biomedical materials, also known as biomaterials, are high-tech materials used to diagnose, treat, repair, or replace damaged tissues and organs, or enhance their functions. With the development of biomedicine and material science, it is hoped that the biomaterials implanted in the human body will only serve as a temporary replacement, and will gradually degrade and be absorbed by the body as the tissue or organ regenerates, so as to minimize the impact of the material on the human body. Long-term effects on the body. Because biodegradable materials are easy to decompose in vivo, their products can be metabolized and finally excreted from the body, and have no toxic and side effects on the body, they have attracted more and more attention and favor from scientists. In recent years, research on a new generation of biodegradable medical metal...
