Possibility of applying a protective layer in the form of a thin metal sheet on flat copper panels of CCM molds by autovacuum brazing was verified on models. 08Kh18N10T steel and nickel were used as protective sheets. Peel strength of bimetal brazed joints between the layers was studied, and bending tests were also performed. A sound brazed seam without defects in the form of pores or cracks was produced between the copper plate and 08Kh18N10T steel sheet 2 mm thick. Peel strength of protective steel layer was equal to 300 MPa, on average. Obtained results allow recommending the method of autovacuum brazing for deposition of protective coatings from 08Kh18N10T steel on flat panels of molds. 9 Ref., 6 Figures.
