2023/11/15/ · Endowing magnesium alloys with both durable antibacterial ability and reliable corrosion resistance is an urgent task for the development of magnesium-based implants. In this work, Mg–Mn layered double hydroxide (LDH) intercalated with organic salicylic acid (SA) anion was synthesized on a PEO-coated Mg–Ag–Mn alloy via the

2021/1/19/ · In this study, a composite coating with outstanding corrosion and wear resistance was successfully produced on LA43M substrates. The composite coating was composed of cold-sprayed aluminum, anodized Al2O3 and a SiO2 sealing coating, which was defined as the MAC composite coating. The properties of the MAC composite

2018/5/15/ · Cr is the most crucial element for the corrosion resistance of Fe-Cr based alloys. Easily formed chromium oxides and chromium oxyhydroxides serve as stable and compact passive films [[56], [57], [58]]. The formation of the Cr-depleted zones in Fe-based amorphous alloys and stainless steels can lower the corrosion resistance [30, 31, 59].

2019/8/8/ · Polyetheramine (D230), an epoxy curing agent, was grafted on graphene oxide (GO) surfaces, which can be stably dispersed in a waterborne curing agent for more than 8 months. Waterborne epoxy coatings reinforced by D230-functionalized GO (DGO) were prepared on carbon steel surfaces. According to the electrochemical impedance

2022/2/7/ · Here we show, by engineering crystallographic con figurations upon metal matrices adjacent. to their passive films, we obtain great enhancement of corrosion resistance of. FeCr15Ni15 single
