COPPER ALLOY POWDER MAKING BY WATER ATOMISATION
Abstract
Water Atomization for metal powder is an appropriate method for producing metal powder from different kinds of metal. Typically, a water atomizing machine is designed with a molten metal spraying chamber in a vertical or horizontal orientation depending on a nozzle design, a molten metal spraying chamber and related components. The main variables influencing the working condition of the water atomization process, which affect sizes, shapes and distribution of metal powder particles, are water pressure, water flow rate, a temperature higher than melting point of liquid metal and flow rate of liquid metal. The water atomizing machine in the study was designed and constructed in which the variable values mentioned could be adjusted. The metal powder produced with the water atomizing machine was from copper. Copper Alloy powder is used for making engine bearings. It will be produced by using water atomisation, even though centrifugal atomisation and gas atomisation is there. Water atomisation is selected due to mass production of copper powder and it is cheap in cost.
