医用金属表面的钽涂层制备及其临床应用趋势

The fabrication of tantalum coating on biomedical metal materials and its clinical application trend

金属钽具有极佳的耐腐蚀性和优异的生物相容性,目前受到越来越多的医学和材料科学工作者的关注,但其高昂的原料成本限制了其在生物医用领域的广泛应用,因此人们采用多种方法制备钽涂层以降低成本。该文综述钽的生物学优势,医用金属(不锈钢、钛合金、钴铬合金)表面的钽涂层制备及其临床应用趋势。

Tantalum has attracted much attention due to its excellent corrosion resistance and biocompatibility. However, the relative high cost of material has dramatically restricted its clinical application as biomaterial. Therefore, various coating fabrication methods have been used to reduce the cost. In this paper, the biological advantages of tantalum, current situation of the fabrication of tantalum coating on stainless steel, titanium alloy, as well as cobalt-chromium alloy, and the prospects of tantalum clinical applications were summarized.
