摘要

A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, includes the following operations or steps: a) providing a base element made of a magnetic or magnetizable material, b) carburizing and/or nitride-hardening of at least one subarea of the base element by diffusion of carbon and/or nitrogen under thermal treatment for forming a non-magnetizable structure in the area of the diffusion zone, and c) finishing the base element so created until an intended geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines.
