Another melting method could be also applied – spraying of powder composition on cold restored component and subsequent melting by gas flame, dielectric heat, and thermal vacuum or by inert-gas shielded welding.
This method could be applied for restoration of a greater number of similar components or for protective coatings.
Thermal conductivity of the consolidated materials was also examined, and its relation to porosity was elaborated.
Powder melting is a process based on spraying of powder on a red-hot metal and melting it by the same flame.
Vacuum Induction Melt, Inert Gas Atomizers Screening is performed to classify powder to a desired size range, down to a maximum particle size of 45 microns (-325 mesh).
For applications requiring finer powder, other separation methods can be employed.
Other products include sintered filters, porous oil-impregnated bearings, electrical contacts and diamond tools.Through a full range of atomizers, alloys can be produced in heat sizes ranging from one pound up to 8,000 lb.in the world's largest vacuum induction melt (VIM) inert gas atomizer designed and built by ATI Powder Metals.In order to measure the thermal conductivity of metal powder, a theoretically verified method which was previously developed by the authors was used.Determination of thermal conductivity of consolidated material was analysed using laser flash technique.One of the important properties in SLM is thermal conductivity of metal powder.
