Abstract
A piece to be magnetized and a covering cap are brazed together to a member, such as a spring seat for a diesel engine injector needle lift sensor. The entire assembly is then subjected to a vacuum ion treatment to case-harden at least the cap and the wear surface of the member. Either before or after the member is case-hardened, the assembly is subjected to an electromagnetic field to magnetize the piece through the cap.
