由于纳米结构表面的许多应用-包括在生物材料中-对其制造的成本和时间有效的方法有强烈的兴趣。在此之前，我们的团队建立了一种简单的电化学方法，在许多不同金属表面的大面积上产生纳米级图案。它们由大约6-10 nm深的凹坑组成，并且以大约50 nm的可调周期性六方闭合填充。排序需要仔细调整表面化学，这使得这些发现转化为多组分合金不明显。在这里，我们首次证明，这样的图案也可以在合金，即Ti-6Al-4V的表面上实现。这种合金对于生物医学植入物特别有意义。虽然之前已经报道了主要成分金属钛和铝上的凹坑形成（尽管条件彼此不同），但我们现在也报道了纯钒表面上的凹坑形成发生在V…
Due to the many applications of nanostructured surfaces – including in biomaterials – there is a strong interest in cost- and time-efficient methods for their fabrication. Previously, our group established a simple electrochemical method generating nanoscale patterns on large areas of a number of different metal surfaces. They consist of dimples that are around 6-10 nm deep and hexagonally closed packed with a tunable periodicity of around 50 nm. Ordering requires careful tuning of the surface chemistry, which makes the translation of these findings to multi-component alloys non-obvious. Here, we demonstrate for the first time that such a pattern can also be achieved on the surface of an alloy, namely Ti-6Al-4V. This alloy is of particular interest for biomedical implants. While dimple formation on the main component metals titanium and aluminum has previously been reported (albeit under conditions that differ from each other), we now also report dimple formation on pure vanadium surfaces to occur under v...
