Abstract

A method is described for making an armature-print wire assembly. The method consists of using powder metallurgy techniques for making the armature and positioning the print wire as an insert into the armature portion. A suitable powder, such as iron (Fe), silicon iron (SiFe) alloy, or nickel iron (NiFe) alloy, is pressed around the print wire. The wire is made of a suitable material, such as tungsten (W), tungsten rhenium (WRe), or tungsten carbide (WC).

Method for Making Armature Print Wire Assembly

A method is described for making an armature-print wire assembly. The method consists of using powder metallurgy techniques for making the armature and positioning the print wire as an insert into the armature portion. A suitable powder, such as iron (Fe), silicon iron (SiFe) alloy, or nickel iron (NiFe) alloy, is pressed around the print wire. The wire is made of a suitable material, such as tungsten (W), tungsten rhenium (WRe), or tungsten carbide (WC).

The entire armature-print wire assembly is sintered to obtain the desired physical properties. The sintering operation provides a bond between the wire and the armature by diffusion bonding. The photograph shows a section taken through an assembly consisting of an iron (Fe) armature and a nickel chromium (NiCr) wire.

This method increases the bond strength between the wire and the armature, and reduces the cost of the assembly.
