The Effect of Hydrofluoric Acid Etching Duration on the

Conclusions The following conclusions were drawn:(a) An increase in the hydrofluoric acid etching duration significantly alters the surface microstructure and increases the surface roughness and wettability of silica based ceramics; (b) etching for longer times results in an increased number and width of the pores (Figure 6), and the width of the pores increases at a faster rate than does the depth Effect of acid etching on tridimensional microstructure of The Effect of Hydrofluoric Acid Etching Duration on the Surface Micromorphology, Roughness, and Wettability of Dental Ceramics Ravikumar Ramakrishnaiah , A. Alkheraif , D. (PDF) Effect of acid etching and collagen removal on Acid etching increased dentin roughness and wettability and no differences were found between acids tested. Dentin wetting and roughness was higher on deep dentin. Effect of acid etching and collagen removal on dentin Average roughness was determined with a profilometer. The specimens were analyzed just after being ground, after etching with 35% H 3 PO 4 gel for 15 s, and after etching and deproteinization with 5% NaOCl for 2 min. Data were analyzed with twoway ANOVA and NewmanKeuls multiple comparison t test procedure. Etching resulted in an increase in surface roughness and dentin wettability. The Effect of Lithium Disilicate Ceramic Surface Mar 09, 2018 · Ramakrishnaiah R, Alkheraif A A, Divakar D D, Matinlinna J P, Vallittu P K (2016) The effect of hydrofluoric acid etching duration on the surface micromorphology, roughness, and wettability of dental ceramics. Int J Mol Sci 17:822839. Article Google Scholar 11. Inspection of chemically roughened copper surfaces using Aug 01, 1995 · The authors are investigating the effects of surface roughness on the wettability and solderability behavior of several different types of copper board finishes. In this paper, the authors present roughness and solderability characterizations for a variety of chemically-etched copper substrates. Profile Characterization and Temperature Effect on the to discuss the wetting phenomenon for but the complexity of this a long time multi-scale phenomenon still has left much to be understood. Since Wenzel reported the effect of roughness on surface wettability [10], re-searchers found the way to enhance the wetting by modifying the surface roughness. Effect of acid etching and collagen removal on dentin Nov 01, 1999 · The specimens were analyzed just after being ground, after etching with 35% H(3)PO(4) gel for 15 s, and after etching and deproteinization with 5% NaOCl for 2 min. Data were analyzed with two-way ANOVA and Newman-Keuls multiple comparison t test procedure. Etching resulted in an increase in surface roughness and dentin wettability. Contribution of surface energy and roughness to the Jul 06, 2015 · The contributing effect of plasma treatment for O 2 etching and hexamethyldisiloxane (HMDSO) vapor coating on the wetting properties was investigated for polyamide 6 (PA6) and polypropylene (PP) substrates. The surface energy components of PA6 and PP were analyzed by the OwensWendt model, and were associated with the wettability of water and
