cryogenictreatments increased both hardness and elastic limit of a low-carbon martensitic stainless steel, while its tribological performance was enhanced marginally.

controlling with high precision the applied force, and measuring the topographical modifications and the friction forces.
The purpose of this paper is to deepen the understanding of the influence of cryogenictreatments on the wear resistance and the mechanical properties of a low-carbon AISI 420 martensitic
