  • Surface modifications of maraging steels used in manufacturing of moulds and dies
    Cajner, Franjo ; Landek, Darko ; Leskovšek, Vojteh
    Low carbon high alloyed, precipitation hardenable MARAGING steels have been developed in early sixties of last century as a high strength structural material dedicated to application in aeronautic ... and missile engineering. Due to excellent properties such as: high hardenability, good toughness, high resistance towards the thermal fatigue, simple heat treatment ("distortionless" and without protective atmosphere) and MARAGING steels are successfully used for the fabrication of various moulds and dies. Despite the listed advantages, the main drawback of these steels is their relatively low wear resistance, particularly if the die is subjected to extensive wear during its service. The paper presents an overview of existing MARAGING steels used in moulds manufacturing and gives their general properties. Also, the results of the applied modification and coating processes are presented with special focus on the increase in wear resistance.
