Features of elastoplastic deformations of composite iron-nickel coatings and their impact on the intensity of wear

Abstract

The paper presents some features of elastoplastic deformation and brittle fracture of iron-nickel composite coatings obtained at electrolyte deposition. Physico-mechanical characteristics (Hh; Hd; Ae; Ap; A; P; Нh/Е; Нd/Е) can be used to improve the description of wear rate of iron-nickel coatings.

Lucrarea prezintă caracteristicile deformaţiilor elastoplastice şi a ruperii fragile a acoperirilor compozite de fiernichel obţinute prin depunerea electrolitică. Caracteristicile fizico-mecanice (Hh; Hd; Ae; Ap; A; P; Нh/Е; Нd/Е) pot fi utilizate pentru a perfecţiona descrierea vitezei de uzurăa acoperirilor de fier-nichel.
