Surface tension of liquid metal under plasma environment

Effect of Plasma on surface tension of liquid SUS 304 stainless steel containing various Sconcentration were measured in a wide temperature range and the following results wereSurface tension of liquid SUS 304 stainless steel decreases with increasing Sconcentration and sulfur acts as surface active element.2.Temperature coefficient of surface tensionof liquid stainless steel depends on sulfur concentration and can be written as follows；γ=176-0.12(T-1480) mN/m…10ppmSγ=1530+0.29(T-1480) mN/m…110ppmSγ=1380+0.49（T-1480）mN/m 250 ppmsc3 . it can be considered that sulfur is adsorbed at the liquid stainless steel surfaceas ionic state which is calculated from a maximum surface excess quantity.4.Plasma does not effecton the surface tension of liquid stainless steel in the present work.5.Density of liquid stainlesssteel can be expressed as；ρ= 7.04 -0.616 (t-1480) g / cm13
