23 Jul Preparation method of gadolinium-molybdenum-cobalt alloy and polyamide stent material
Abstract
The invention belongs to the technical field of biomedical materials, and relates to a preparation method of a gadolinium-molybdenum-cobalt alloy and polyamide stent material. The preparation method of the stent material comprises the steps of cleaning and surface modifying of a polyamide stent material, catalytic activating and chemical plating of a gadolinium-molybdenum-cobalt alloy. The preparation method has the advantages that the organic carbon overflow rate of the stent material is decreased by 99% or above, the Mohs hardness can reach 6.1, and according to a test which is used for simulating body fluid corrosion for 180 days, the metal ion overflow rate is smaller than 1 ppm, that is to say, the material has extremely high biological environment reliability. The gadolinium-molybdenum-cobalt alloy and polyamide material can be used for tissue engineering stent materials and is bright in application prospect and huge in market potential.
