简介：来临三维(3-D)打印了技术在设定的多孔的钛(Ti)的制造提供大可能性植入。然而，打印Ti的bioinert性质提出一个突出的问题。混合微弧的氧化并且热水(MAO-HT)多孔的金属上的处理能生产multi-scaled层次矫形植入，为3-D的表面修正的出现大潜力打印了植入。在这研究，有毛孔的圆柱的多孔的Ti6Al4V(Ti64)脚手架640缩放吗？？

简介：ZrC涂层被低压力在石墨底层上扔有Br的化学蒸汽免职(LPCVD)2-Zr-C3H6-H2-Ar系统。微观结构和ZrC涂层的生长行为上的免职时间的效果被调查。ZrC涂层在一个岛层模式成长了。涂层的形成被ZrC的成核统治在起始20分钟，和快速的成核产生了ZrC的有细密纹理的结构涂层。免职时间什么时候在30min上，涂层的生长被统治由晶体，给安排列的结构。精力散X光检查光谱学证明到锆的碳的臼齿的比率在在ZrC涂层，和X光检查的1:1附近显示出的光电子光谱学ZrC是在涂层的主要阶段，由大约2.5mol%伴随了ZrO2次要的阶段。
