Description
Technical Field

Background
Metal powder refers to a group of metal particles having a size of less than 1mm, including single metal powders, alloy powders, and powders of certain refractory compounds having metallic properties, which are the main raw materials for powder metallurgy. The metal powder is prepared mainly by mechanical grinding and crushing, atomizing and the like.
Mechanical comminution is the process of breaking solid metal into powder by crushing, breaking and grinding. The method has low efficiency and large energy consumption, irregular sharp corners appear on powder particles, and the powder flowability, the apparent density, the tap density and the like are reduced; meanwhile, impurity elements are introduced due to contact with grinding media of different materials, so that the purity of powder and the comprehensive performance of a subsequently prepared metal component are influenced.
The atomization method is that large solid metal is heated at high temperature to become molten metal, the molten metal is atomized into fine liquid drops by a cooling medium, and the fine liquid drops are solidified into powder in the cooling medium. There are mainly two methods, gas atomization and liquid atomization. There are also centrifugal atomization methods using spinning disk pulverization and rotation of the melt itself (consumable electrode and crucible), and other atomization methods such as hydrogen-dissolved vacuum atomization, ultrasonic atomization, and the like. The gas atomized powder is generally nearly spherical, and irregular shapes can be obtained by water atomization. However, the method has expensive equipment and high energy consumption, and simultaneously, impurities are easy to generate or mix in the product, which affects the purity of the powder and the comprehensive performance of the metal component prepared subsequently.
