Additional researches of wetting contact angle of quartz glass, supphire, teflon, graphite and zinc stearate surfaces by water, glycerin, hyposulfite and phosphoric acid solutions were carried out. The design of quartz-metal cassetes and device design for research of wetting contact angle of solids by melted metals under action on them centrifugal forces (up to 22 go) have been modified. The modified stand for research of wetting contact angles of solid nonmetallic surfaces by melted metals was designed and fabricated. As a results of the works were executed in 2013 it was established. that for each concrete system liquid (including melted metal) - solid surface the wetting contact angle have been constant irrespective of the sizes of drops and also from action of centrifugal force. Thus, the results of researches were received on the Earth testify that Young equation is true in its present kind in which the equation does not include acceleration of terrestial gravitation go.
