“…This native oxide layer should act as a barrier to dislocation motion during mechanical straining thus should improve mechanical properties of the profiles as in case of Al-based PM material made through direct extrusion as published by Balog et al [25]. Moreover, based on literature [26,27], such native envelope could act as a barrier to corrosion and improve biodegradable properties of Mg as in case of surface-treated powders WE43 with HF [28].…”

Magnesium-based biomaterials are good candidates as a new generation of biodegradable metals since magnesium (Mg) can dissolve in body fluid. Therefore, implanted Mg can degrade during the healing process, and if the degradation rate is controlled no debris after completion of healing is expected. Besides its biocompatibility, inherent mechanical properties of Mg are very similar to those of human bone. This paper is focused on the possibility to prepare the pure Mg material from powders with further intention to use it as a biodegradable implant. Powders were consolidated via cold compaction to prepare the extrusion billets which were subsequently directly extruded to final profiles at a controlled temperature to avoid the formation of the thick oxide layer. The microstructure is revealed through SEM, SEM--EBSD, TEM, and HRTEM and mechanical properties are determined via a uniaxial tensile test. Results are compared with Mg ingot and WE43 alloy, which is commercially used for biodegradable (biocompatible) material.

“…Cui et al fabricated a MAO/zinc stearate (ZnSA) composite coating with micro plate-like structure by MAO processing and electrochemical deposition method [75]. The hydrophilic coating was produced first by MAO in phosphate-containing electrolyte, then followed by the roughness control process and low surface energy material deposition to obtain the super-hydrophobic coating.…”

Corrosion—reactions occuring between engineering materials and their environment—can cause material failure and catastrophic accidents, which have a serious impact on economic development and social stability. Recently, super-hydrophobic coatings have received much attention due to their effectiveness in preventing engineering materials from further corrosion. In this paper, basic principles of wetting properties and corrosion protection mechanism of super-hydrophobic coatings are introduced firstly. Secondly, the fabrication methods by electrochemical surface engineering—including electrochemical anodization, micro-arc oxidation, electrochemical etching, and deposition—are presented. Finally, the stabilities and future directions of super-hydrophobic coatings are discussed in order to promote the movement of such coatings into real-world applications. The objective of this review is to bring a brief overview of the recent progress in the fabrication of super-hydrophobic coatings by electrochemical surface methods for corrosion protection of engineering materials.

“…Creating durable surfaces for aluminium and its alloys that withstand corrosion in underwater environments is of great importance for marine and energy-related applications [1][2][3]. Surface anodization has been widely used to improve the corrosion resistance of aluminium by forming protective anodic aluminium oxides (AAO) consisting of a thin and compact barrier layer and a thick porous layer [4,5].…”
