Abstract

W sposobie wyznaczania lepkości i napięcia powierzchniowego ciekłego metalu upuszcza się kroplę o średnicy z zakresu 0,3 – 5 mm badanego ciekłego metalu w temperaturze z zakresu od temperatury topnienia do temperatury wyższej o 500 K, z wysokości wybranej z zakresu 50 – 500 mm na powierzchnię drgającą z zadaną częstotliwością ultradźwiękową, doprowadzając do atomizacji kropli ciekłego metalu, przy czym powierzchnia drgająca jest nachylona pod kątem z zakresu 5 — 75 stopni względem poziomu, a następnie prowadzi się pomiar wielkości zatomizowanych cząstek ciekłego metalu i wyznacza napięcie powierzchniowe σ oraz lepkość µ ciekłego metalu. Sposób znajduje zastosowanie w metalurgii i przemyśle odlewniczym.
