A novel ultra-smoothing process for aluminum surfaces was developed using porous alumina formation and subsequent oxide dissolution. submicron-scale periodic dimpled surface with an arithmetic mean roughness of 31.5 nm prepared by anodizing in etidronic acid solution. This specimen then anodized a sodium metaborate (NaBO 2 ) solution to form unique film extremely flat barrier layer, which diffe...

Abstract FeCo-based soft magnetic alloys are commonly used in macroscale devices to improve its electromagnetic performance, whereas they have been barely the microscale. Current FeCo alloy micromanufacturing processes present some difficulties like low structural strength, oxidation at high temperature processes, stoichiometry mismatches deposition and tough workability. In this work, a microc...

Improving the interfacial properties between electrode materials and current collectors plays a significant role in lithium-ion batteries. Here, four kinds of electrolytic copper foils with roughness (Rz) values 1.2, 1.5, 2.2, 2.8 μm were prepared via an electropolishing technique. Reducing foil can effectively improve wettability anode slurry. The value 1.2 shows best coating uniformity graphi...

Cavities and ageing leads to a higher demand for robust and durable dentures. Cobalt chromium dental cast alloys fulfill these requirements. After the casting, the alloys have to be thoroughly cleaned in an electrochemical dissolution bath. In the existing technology an expert has to control the polishing process. In this paper we present a fuzzy logic controller with 16 fuzzy rules, which comp...
