Abstract

Til fremstilling av et ekspansjonsanker av et korrosjonsbestandig stål blir det for oppnåelse av gunstige og varige glideforhold og til reduksjon av tæringstendensen foreslått en fremgangsmåte hvor utgangsmaterialet, fortrinnsvis for ekspansjonslegemet, anrikes med interstitielt løste, ikke-metalliske legeringsbestanddeler såsom karbon, nitrogen og/eller bor. Deretter utskilles disse legeringsbestanddeler ved en eldringsglødning i form av karbider, nitrider og/eller borider for oppnåelse av en øket hårdhet.
