摘要：在低压Ar等离子体条件下，在1823~2073 K温度范围内，测量了硫含量分别为10、100和250 ppm的304不锈钢的表面张力和密度。测量采用座滴法，采用(La0.9Ca0.1)CrO3基体。没有观察到等离子体对表面张力及其温度系数的显着影响。 304不锈钢的表面张力和密度用以下方程表示：

AbstractThe surface tension and the density of 304 stainless steels with the sulfur contents of 10, 100 and 250 ppm were measured under low pressure Ar plasma conditions in the temperature range of 1823–2073 K. The measurements were carried out by the sessile drop method and a (La0.9Ca0.1)CrO3 substrate was used. No significant influence of the plasma was observed on the surface tension and its temperature coefficient. The surface tension and density of 304 stainless steel are expressed using the following equations:
