Abstract: A method for modifying a dimension of a cast iron pump part features placing a cast iron pump part on a base plate of a directed energy deposition (DED) machine; selecting a metal deposition procedure for depositing a metal having a combination of one or more Nickel Alloys or Nickel powders on the cast iron pump part; and depositing the metal on the cast iron pump part to modify the dimension of the cast iron pump part, based upon the metal deposition procedure selected. The selecting of the metal deposition procedure includes forming the metal by mixing metal powders that include a Nickel Alloy “A” in a specified mixed ratio with a pure Nickel powder “B” for depositing on the cast iron pump part.
