This process is a method of producing powders of varying grain size for use as:
Bearing surface coating
Sintered products - welding rods etc.
Isostatically pressed parts such as gear wheels, valve seats and magnets
Home, garden and leisure products
Melting is carried out in high frequency or induction type furnaces. The weight of the melt is generally small with a 200kg charge considered average and a 5-6 tonne charge very large. Cleanliness is paramount during the production process especially with the melting and atomisation of super alloys where any contamination would not be tolerated.
Iron powders can be melted by electric arc furnace or other bulk melting operation. Consequently, the melt size is larger e.g. up to 50 tonnes.
Molten metal temperatures prior to atomisation can range from 800°C (lead/aluminium alloys) to more than 2000°C (super alloy production). Process times are generally measured in minutes but new machines are being designed to operate on a more continuous basis of up to 24 hours.
The actual atomisation or conversion of the molten metal stream to powder is achieved by bombarding the stream with a high pressure jet of air, inert gas or water.
Main Benefits of Spark Atomising Nozzles:
SPARK OZA Yttria stabilised zirconia with excellent erosion resistance properties. High temperature resistance suitable for super alloy and nickel based alloys.
Ceria and magnesia stabilised zirconia with excellent thermal shock resistance. Suitable for high temperature production of super alloys and nickel based alloys.
Dyson composite nozzles comprise a high density Zirconia insert and an Alumina outer body. Composite nozzles can aid longer casting sequences and can be installed more easily and accurately than traditional Atomising Nozzles. Dyson manufactures an extensive range of composite nozzle designs.
