Corrosion Protection of 6061 Aluminum Alloys by Sol-Gel Coating Modified with ZnLaAl-LDHs
نویسندگان
چکیده
In this work, ZnLaAl layered double hydroxides (LDHs) were prepared by the co-precipitation method, and ZnLaAl-LDHs nanosheets embedded in sol-gel coating for corrosion protection of 6061 aluminum alloys. The structure, morphology, long-term anti-corrosion performance modified with investigated. structure morphology analysis showed that are finer than those ZnAl-LDHs, results suggesting La can refine size LDHs’ improve their nucleation rate. tests exhibits higher resistance better stability compared which indicates addition enhances LDHs improves LDHs. Finally, formation mechanism on alloys both discussed detail.

CORROSION RESISTANT SOL–GEL COATING ON 2024-T3 ALUMINUM
The inherent reactivity of the Al–Cu alloys is such that their use for structural, marine, and aerospace components and structures would not be possible without prior application of a corrosion resistance system. Historically these corrosion resistance coatings were based on the use of chemicals containing Cr (VI) compounds. Silane coatings are of increasing interest in industry due to th...
متن کاملInvestigation of corrosion protection properties of TiO2-CdO nanocomposite coating prepared by sol-gel method on copper
the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...
متن کاملOrganic-inorganic sol-gel coating for corrosion protection of stainless steel
One of the most effective corrosion control techniques is the electrical isolation of the anode from the cathode [1, 2]. The chromium oxide (Cr2O3) passivation layer formed on the surface of stainless steel in oxidizing environments is one example. This is the main reason for the durability and corrosion resistance behavior of this particular metal [2, 3]. A more generic approach to enhance cor...
متن کاملTrivalent Chromium Conversion Coating for Corrosion Protection of Aluminum Surface
Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...

To improve the corrosion protection of copper metal, 0.01M concentration of 1H-1,2,4-triazole-3-thiol (TAT) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS). It was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. The TAT-doped hybrid sol-gel coating was applied over the c...
