Vol. 4, no. 1

38--41

Object of interest in the article is the method of metal spraying from the liquid phase (gas atomization method). Process involves melting of metal alloy and its subsequent spraying with the stream of inert gas. The quality of obtained powders depends largely on the properly conducted spraying, which results in powders properties – such as volume distribution and size of particles. Therefore, gas atomization method and relevant powders properties are reviewed. Experimental part covered investigations of alloy of tin, antimony and copper from the point of view of their volume fractions and chemical composition. It was concluded that method of metal spraying from the liquid phase enables ease control of grains geometry and assure high quality of manufactured powders.
