Sealing treatment is a post-surface of the plasma spray coating process to improve corrosion resistance material. In this study, effect sealing on and adhesive strength spray-coated alumina coatings was analyzed. For sealing, an epoxy resin applied surface coated specimen using brush. The subjected salt test for up 48 hours microstructural analysis revealed that in layer/base material interface...

The effects of sandblasting media and steam cleaning treatment after sandblast were examined on tensile bond strength of porcelain to titanium. The use of the commercially available silica-coated alumina particles for sandblast was significantly effective for increasing bond strength than the conventional alumina. It might be due to the increased surface roughness and existence of remaining sil...

Abstract The lubricity of coatings made from different types carbon nanoparticles such as onions, nanohorns and nanotubes is investigated on line-patterned AISI 304 stainless-steel substrates using ball-on-disc tribometry over 200,000 sliding cycles. Picosecond direct laser interference patterning used to create line-patterns the substrate surfaces which are subsequently coated by electrophoret...

Cysteic acid functionalized mineral oxide nanoparticles can be used to impart superhydrophilic performance on a range of woven and non-woven fabrics. Woven fabrics spray dip coated alumina iron based cysteic nanoparticles, were characterized by SEM, EDX the change in water contact angle was measured or where increased hydrophilicity sufficiently great that time for adsorption droplet measured. ...

The mechanical behavior in liquid lead of the 15-15Ti steel coated by an alumina layer and Alumina Forming Austenitic (AFA) steel, with a chemical composition allowing for formation at surface has been studied. To investigate metal embrittlement (LME) sensitivity lead, tensile tests air have carried out 400 °C 500 °C. Then analyses cracking fracture surfaces performed. No LME tested conditions ...

in the present work, a new kind of alumina-based adsorbent with high selectivity and stability and efficient adsorption was prepared. alumina was coated with an oxazolone azo dye, 2-(4-{2-[4-(dimethylamino) phenyl]-1-diazenyl}phenyl)-4-[1-phenyl methylidene]-5(4h)-oxazolone, and then used for preconcentration of trace amounts of palladium. the analytical procedure involved the complex formation...

The objective of this study was to investigate the effect of hydrofluoric acid etching treatment on the surface characteristics of zirconia and Streptococcus sanguinis (S. sanguinis) and Porphyromonas gingivalis (P. gingivalis) biofilm formation on zirconia. Zirconia specimens were prepared with different treatments, including being polished with 1000-grit SiC abrasive paper as the control grou...
