sealing treatments for electrochemical conversion coatings
Sealing structure, composition , and mechanism differ according to the sealing process type and the constituents of the sealing solution. Figure 24.1 shows a schematic graph of the conversion coating before and after a sealing treatment in a chemical conversion solution containing corrosion inhibitors. The surface of the conversion coating has many pores and cracks, as explained in the ...
new sealing treatment of microarc oxidation coating
Silanisation treatment was proposed as a new approach for sealing treatment of microarc oxidation (MAO) coating on Mg alloy AZ91D. The morphologies of the Mg alloy surfaces after MAO with or without silanisation sealing treatment were characterised by scanning electron microscopy.
effect of porosity sealing treatments on the corrosion resistance of ...
After the sealing treatment by the three sealants, the big pores on the coating surfaces are almost sealed, as seen from Fig. 2 b–d. In fact, with the Na 3 SiO 4 sealant, the sealing operation must endure very slow impregnation and cure cycles. The sealing treatment only takes effect on the surface layer of the coatings (Fig. 2 b).

This study investigated the corrosion morphology of arc-sprayed Zn and Zn85-Al15 coatings with and without sealing treatment under simulated defect conditions. The hole sealing treatment was carried out by Conventional Impregnation Sealing (CIS). The performance of two coatings was assessed by employing morphological analysis, chemical composition, and electrochemical studies.
effects of sealing treatment on corrosion resistance and degradation ...
The effects of three different sealing treatments on micro-arc oxidized (MAO) medical magnesium alloy wires using boiling water, zirconia sol–gel, and organic gelatin–hydroxyapatite (HA) coatings on the surface morphology, corrosion resistance, and degradation behavior in simulated body fluid (SBF) and simulated intestinal fluid (SIF) are investigated.
