This paper studies the influence of small additions of bismuth and tin on the surface tension of Wood's alloy, the equilibrium contact angle, and the work of adhesion when crystals are wetted with the solder alloy, as well as on the value of the contact resistance. The specimens for the investigations were cut from single crystal boules of compositions Bi/sub 91/ Sb/sub 9/, Bi/sub 93/ Sb/sub 7/, and Bi/sub 94/ Sb/sub 6/, which were grown by the Czochralski method of pulling from the liquid phase with a concurrent replenishing supply of solid antimony to the melt. It has been shown that small additions of bismuth and tin to solder significantly affect the adhesion and electrical phenomena at the interface between the solder and crystals of solid solutions. A correlation has been found between the adhesion characteristics and the electrical characteristic of contacts obtained at the interface between the indicated crystals and Wood's alloy.
