摘要
对固体粒子进入熔体的条件及影响因素进行了讨论。建立了粒子进入熔体的热力学条件 ,指出只有润湿角等于零时 ,粒子才能自发地完全进入熔体中 ,否则需要克服一能量障碍 ;得出了粒子单在自身重力作用下自发进入熔体的临界尺寸、考虑粒子浓度时使粒子进入液体所需外力的功的表达式 ,以及粒子进入熔体的动力学条件。所得结论与试验结果吻合良好。
The conditions of the entry of solid particles the melt and influence factors on it were discussed. The thermodynamic condition of a solid particle entering the melt was established, which illustrated that the condition of a particle completely entering the melt spontaneously is zero contact angle and an energy barrier must be overcome even if the contact angle is less than π/2. The critical particle size, equation of work and kinetic condition needed for particles to completely enter the melt were also obtained.
