METALLIC COMPOSITE COMPONENT, IN PARTICULAR FOR AN ELECTROMAGNETIC VALVE |
摘要 |
The composite component according to the invention is characterized by the provision of at least two portions (61, 62) of different magnetization, wherein the at least two portions (61, 62) lie directly in succession on the integral component (60). The starting material of the composite component (60) is a semi-austenitic steel. A first portion (61) has a higher saturation polarization Js than an adjacent second portion (62), wherein the second portion (62) has a minimum saturation polarization Js of 0.1 T to 1.3 T and/or a maximum relative permeability µr of 2 to 150. The composite component (60) is particularly suitable for use in electromagnetic valves, e.g. also in fuel injection valves of internal combustion engines. |
