technology allows for 3D printing. Its most notable advantage is the ability to generate parts in any shape directly from computer graphics data, without any machining and molds. This greatly reduces the product development cycle while increasing productivity and reducing costs. Metal powder, the main raw material in 3D printing metal parts, has caught people’s interest. 3D Printing Metal Powder is also valuable because it is the most important component of the 3D Printing Industry Chain of metal parts.
Metal powder preparation
The metal powder preparation processes can currently be classified as reduction, electrolysis and carbonyl decomposition methods, grinding and atomization. Depending on the preparation process. In the powder metallurgy sector, powders produced by reduction and electrolysis are the most commonly used raw materials. The atomization technique can be used to make alloy powder. A modern atomization procedure can also control powder shape. The development of the atomization cavities has greatly improved the efficiency of atomization, making the atomization technique the most popular method to produce powder. The atomization technique meets the specific requirements of 3D printed consumable metals powder. The atomization process is a mechanical method for pulverizing the molten metal to particles of a size less than or equal to 150 mm.
The water atomization process is one of the cheapest methods of production for atomized powder. The atomization media water is cheap, easily available and has excellent atomization. The domestic water atomization technique is used mainly to produce steel, matrix powder for diamond tool, pre-alloy, powder for oil-bearing, powder for hard surfaces technology, and iron and nickel-based magnet powders. The specific heat of water being much greater than the gas’s, it is possible that the metal droplets will solidify and become irregular during the atomization. Water will react with other metals or alloys that have a high level of activity. In addition, contact with the water during the atomization will increase the amount of oxygen in the powder. This limits the use of water atomization for metal powders of high sphericity with low oxygen contents.
