摘要： Since a surface of an iron powder is covered with an oxide film composed of a Si-based oxide in which the ratio of Si to Fe satisfies Si/Fe≧0.8 on an atomic number basis, an iron powder for dust cores is provided which can be formed into a dust core having a high resistivity and hence having a low iron loss without degrading the mechanical strength.

摘要： An ultrasonic welding tool fabricated of powder metal material includes a body and a welding tip extending axially from the body to a working end. The powder metal material can be ferrous-based and admixed with additives, such as alumina, carbide, ferro-molybdenum, ferro-nickel, chrome or tribaloy. An exposed surface of the welding tip can comprise Fe3O4 oxides. The tool is compacted to the desired shape and sintered. The body can include a different second material compacted separately from the welding tip and then joined to the tip and sintered.
