Despite their high silicon content up to 17–25 ma% spray‐formed Al alloys are well nitridable. The present paper deals with the influence of the chemical composition, initial surface roughness and the nitriding parameters on the nitriding behavior, especially the surface coverage with aluminum nitride. Furthermore, the hardness and wear behavior are investigated both after the single plasma nitriding treatment as well as an additional subsequent heat treatment (age hardening).
