射频等离子体具有温度高(约104℃)、等离子体炬体积大、能量密度高、传热和冷却速度快等优点,是制备组分均匀、球形度高、缺陷少和流动性好的球形粉末的良好途径。等离子熔融球化技术被认为是获得致密规则球形粉末的最有效手段之一。北京科技大学盛艳伟等人以不规则形状的市售TC4钛合金粉末(粒度小于30μm)为原料,通过射 RF plasma has the advantages of high temperature (about 104 ℃), plasma torch volume, high energy density, heat transfer and cooling speed, etc. It is a kind of spherical powder with uniform composition, high sphericity, few defects and good fluidity A good way. Plasma melting spheroidisation is considered as one of the most effective means to obtain compact regular spherical powder. Beijing University of Science and Technology, such as Sheng Yan Wei and other irregular shape of the commercially available TC4 titanium alloy powder (particle size less than 30μm) as raw material, through the shot
