Title:
HARD PHASE DISPERSED NICKEL GROUP INTERMETALLIC COMPOUND COMPOSITE SINTERED MATERIAL, MANUFACTURING METHOD THEREFOR, AND CORROSION RESISTANT ABRASION RESISTANT COMPONENT USING THE MATERIAL
Document Type and Number:
Japanese Patent JP2019077930
Kind Code:
A
Abstract:
To provide a corrosion resistant abrasion resistant material suitable for use in a corrosion resistant abrasion resistant component such as a cylindrical sleeve for pump shaft or the like, a corrosion resistant abrasion resistant mold, a corrosion resistant abrasion resistant tool or the like, and a manufacturing method therefor.SOLUTION: A hard phase dispersed nickel group intermetallic compound composite sintered material containing a first phase of 35 vol.% to 80 vol.% and a second phase of 20 vol.% to 65 vol.% is obtained by mixing a hard powder (the first phase) consisting of solid solution body of Ti, Mo and/or carbide, nitride or carbonitride of W, and a material (the second phase) containing 75 at.% to 85 at.% of nickel (Ni), 8 at.% to 13 at.% of silicon (Si) and 3 at.% to 13 at.% of titanium (Ti) and becoming a binding material of the hard powder to manufacture a mixed powder or an alloy powder, and heating and sintering the mixed powder or the alloy powder with adding pressure.SELECTED DRAWING: None
