Abstract
State of research of surface properties of metal systems based on Sn, Pb,In and wetting of aluminum and copper by them
Incoming article date: 17.02.2021In this work the data about the surface properties of melts on a base of Sn, Pb, Inare given. It is shown, that the best effect of wetting at brazing alloys Al- 4 аt.% Li is attained with the help of an eutecticum of system stannum - aluminium. It is shown, that at photon bakeout of films of stannum on siliciums within 3-4 seconds improvement of their wetting by melts on a base of stannum is provided. Perspectivity of use of composition solders on a base of copper and a nickel imbued by melts of stannum with small additives alkaline and alkaline-earth elements is marked.
