Crystallization fouling, or mineral scaling, is fundamental to various surfaces in energy and environmental applications. This paper considers, for the first time, a systematic investigation of scaling of nonwetting aluminum and brass surfaces relative to their bare counterparts. Metallic surfaces with a range of nonwetting characteristics from hydrophilic to superhydrophobic and lubricant infused surfaces were fabricated using a facile etching method. Systematic dynamic flow scaling experiments are conducted on the six different surface types at three flow levels and two temperature levels. The interactive effects of the different parameters are analyzed relative to their correspondence to the nucleation theory. The study reveals that nonwetting metallic superhydrophobic or hydrophobic surfaces reduce fouling by over 50% compared to bare counterparts. Lubricant infused metallic surfaces demonstrate superior anti-scaling performance by over 60% and up to 90% fouling reduction. The study is the first to present fundamental insights into the engineering and anti-scaling performance of nonwetting brass and aluminum surfaces.

结晶结垢或矿物结垢是能源和环境应用中各种表面的基础。本文首次考虑对非润湿铝和黄铜表面相对于其裸露对应物的结垢进行系统研究。具有从亲水性到超疏水性和润滑剂等一系列非润湿特性的金属表面注入的表面是使用简单的蚀刻方法制造的。在三个流量水平和两个温度水平下对六种不同的表面类型进行了系统的动态流量缩放实验。相对于成核理论的对应关系，分析了不同参数的交互作用。该研究表明，与裸露的对应物相比，非润湿金属超疏水或疏水表面可减少 50% 以上的结垢。注入润滑剂的金属表面表现出卓越的防垢性能，可减少 60% 以上和高达 90% 的污垢减少。该研究首次提出了对非润湿黄铜和铝表面的工程和防垢性能的基本见解。
