Conclusions

  1. 1.

    The method of preparation of spherical metal powders, based on the melting of powders with irregularly-shaped particles mixed with inert fillers, may be recommended together with the method of atomization of molten metals. Unlike the latter, the melting method does not require any melting equipment or special atomizing devices.

     
  2. 2.

    For raising the strength characteristics of sintered filters from bronze, copper, and nickel powders and lowering their sintering temperature, it is desirable to alloy these powders with phosphorus by adding 1.5–2% of diammonium hydrophosphate to the starting powders.

     
  3. 3.

    The permeability of sintered filters is determined by the particle size of the powder employed, and the porosity and wall thickness of the filter. The data obtained for the effect of these factors on permeability may be recommended for practical utilization.

     
  4. 4.

    At equal permeability, sintered filters secure a higher degree of removal of contaminants from the medium being filtered than paper filters.
