Wettability and Adhesion of Noble Metal (Au, Ag)-Glass Systems
ABSTRACT
In order to estimate the wettability of the borosilicate glasses with different composition on the noble metals of gold and silver, the measurements of the contact angle between the solid and the liquid were made at various temperatures and holding times using the sessil-drop method. The wetting behavior and the adhesion of the phases were strongly influenced by the thermal or the physical characteristics of the materials. The dependence of wetting angle ($theta$) on the holding time (t) could be represented by the relation of $theta$=a.tb, whereby the wettability of the systems was quantitatively compared. Also with increasing content of borosilicate glass in the glass-gold matrix composite, the tensile strength was decreased whereas the elastic modulus was increased.
Key words: Sessile drop, Contact angle, Work of adhesion, Borosilicate glass, Tensile strength, Elastic modulus
