An entirely femtosecond laser (fs-laser) based process for the production of stable, enlarged and alloyed nickel surfaces is presented. The process allows the use of metal foils and aqueous salt solutions as alloying element sources. We alloy iron from an aqueous element source as well as molybdenum and cobalt from commercially available foils on nickel mesh surfaces without further coating process. It is shown that the content of alloyed iron on the nickel mesh surface structured with the fs-laser depends on the concentration of the aqueous iron(II) sulfate solution used. The alloy content of cobalt and molybdenum is controlled by adjustable laser parameters. Cross-sections prepared by a focused ion beam and subsequent energy dispersive X-ray spectroscopy shows that molybdenum and nickel form alloyed nanoscale particles on the structured nickel surface. The combination of an aqueous iron(II) sulfate solution and a molybdenum metal foil leads to a ternary nickel-molybdenum-iron surface alloy. The presented fs-laser alloying process can be applied to further metal combinations and offers the potential to create new materials and properties.

提出了一种完全基于飞秒激光（fs-laser）的工艺，用于生产稳定，扩大和合金化的镍表面。该方法允许使用金属箔和盐水溶液作为合金元素源。我们将镍元素表面的水元素来源的铁以及钼箔和钴从市售箔中合金化而无需进一步的涂覆工艺。结果表明，由fs-激光构成的镍网表面的合金铁含量取决于所用硫酸铁（II）水溶液的浓度。钴和钼的合金含量由可调节的激光参数控制。通过聚焦离子束和随后的能量色散X射线光谱学制备的横截面显示，钼和镍在结构化的镍表面上形成合金化的纳米级颗粒。硫酸铁（II）水溶液和钼金属箔的组合产生三元镍-钼-铁表面合金。提出的fs-激光合金化工艺可以应用于其他金属组合，并具有创造新材料和性能的潜力。
