Study of the influence of metallic nanocoatings on adhesion properties and strength of silicon oxide—aluminium alloys soldering joining

Abstract

The dependence of the strength on the shear of a solid Pb—2,5% (mass.) Ag, Pb—15% (mass.) In, and Pb—40% (mass.) Sn alloys on the thickness of Cr, Nb, Ti nano coatings on silicon oxide was studies. The coatings were sprayed by electron beam evaporation of metals in vacuum. The dependences of the shear strength on the thickness of metal coatings are of the same nature. As the film thickness increases to a threshold value the tensile strength increases. A further increase in film thickness leads to a decrease in shear strength.
