METHOD FOR ELECTROEXPLOSIVE SPUTTERING OF COMPOSITE COATINGS OF Al-TiBSYSTEM ONTO ALUMINIUM SURFACES

摘要

FIELD: metallurgy.SUBSTANCE: method involves arrangement of powder charge from titanium diboride between two layers of aluminium foil and electric explosion of foil with formation of pulse multiphase plasma jet, melting of aluminium surface using it at the value of specific energy flow of 3.8?4.1 GW/mand sputtering onto the molten layer of components of plasma jet, with further self-hardening and formation of a composite coating containing titanium diboride and aluminium.EFFECT: increasing wear resistance and microhardness of a coating; improving its adhesion to base.4 dwg, 3 ex
