Feb 1, 2020 · The enhanced corrosion resistance and biocompatibility were highly related to the morphology of the hydroxyapatite coatings, and the hydroxyapatite coatings with nanowhisker structures clearly had increased corrosion resistance and biocompatibility. In addition, due to the addition of Zn, the coatings had obvious antibacterial activity.
Jan 20, 2022 · The STEM-EDS of SLM-316L and SLM-316L/CrN are presented in Fig. 4a, b.In both the specimens, the columnar cellular boundaries showed segregation of Cr, Ni, Mo, and S and depletion of Fe.

Nov 1, 2022 · The corrosion and wear behaviors of materials are usually sensitive to the microstructural features. In the current work, a novel strategy using laser surface remelting (LSR) to modify the surface microstructure of a precipitate-hardened magnesium alloy was proposed to synergistically enhance the corrosion and wear resistances.
Feb 1, 2023 · 1. Introduction. Reinforced concrete structure (RCS) is one of the most durable and commonly used structure forms in the past decades [1], [2].Nevertheless, concrete has a huge “carbon footprint” and at least 8% of human-caused global emissions come from the cement industry, thus it is urgent to develop low-carbon cement and concrete [3], [4].
Mar 5, 2021 · The main contaminants of concern in manure are veterinary antimicrobials. A ten-year record (2009-2018) of the amount of veterinary antimicrobials sold in the U.S. for disease control (administered at therapeutic levels) and growth promotion (administered at sub-therapeutic levels) in food-producing animals alone have ranged from 10.9 to 15.6 million kg/year (Fig. 1) (USFDA, 2019a).
Feb 7, 2022 · Here we show, by engineering crystallographic configurations upon metal matrices adjacent to their passive films, we obtain great enhancement of corrosion resistance of FeCr15Ni15 single
Nov 12, 2006 · The impingement of solid particles causes damage or breakdown of the passive film and thus accelerates the corrosion process significantly. The additional corrosion component caused by erosion could be termed as erosion-enhanced corrosion. Many researchers have reported serious erosion-enhanced corrosion for passive metallic materials [5], [6
May 30, 2022 · Corrosion resistance is defined as the inherent ability of a material (metallic or non-metallic) to withstand corrosion damage caused by either oxidation or other chemical reactions. Resistance to corrosion can be achieved either through the intrinsic resistant properties of the material or by using corrosion resistant products/substances such
