Influence of the State of the Contact Surfaces on the Formation of the Joint of Steel and Brass during Cold Cladding

Abstract

Joint plastic deformation of the components of bimetal 1 according to OST 3-6648-91 brass L90-steel 18JUA-brass L90 should be produced with the greatest possible compression to obtain the necessary strength of the joining of the layers, ensuring the strip looking into a roll without stratification. Preparation of contact surfaces before cold cladding is one of the most important technological operations. The influence of such factors on the strength of the bonding of bimetal layers as the surface hardening of contact surfaces, the microgeometry of contact surfaces, the temperature of diffusion annealing after cladding, the influence of the ratio of the thicknesses of bimetal layers was investigated. Technological recommendations for the production of bimetal 1 on OST 3-6648-91 brass L90-steel 18JUA-brass L90 by the method of cold cladding are developed.
