Effect of nitriding on wear resistance of iron alloys with various lattice types
Source abstract
Abstract
The paper considers the characteristics of the formation of the wear-resistant structure of nitrided model alloys with bcc and fcc lattices: Fe-Mo, Fe-Cr, Fe-Al, Fe-Ni-Cr, Fe-Ni-Al, Fe-Ni-Ti, and Fe-Ni-Cr-Al-Ti. The relationships between the structure characteristics of the nitrided layer and the wear resistance of the alloys are found. The maximal wear resistance of the alloys with the bcc lattice of the matrix is shown to be attained when incoherent particles of nitrides of the alloying elements appear; the maximal hardness corresponds to the alloy that contains coherent nitrides. In the alloys with the fcc lattice, the maximal hardening under nitriding and the maximal wear resistance are achieved at the stage that precedes the rupture of the coherent bond between the nitride and the matrix. The relationships between the structure characteristics of the nitrided layer and the wear resistance are discussed from the viewpoint of the formation of a wear-resistant structure state of the alloys.
