PROCESS FOR JOINING STAINLESS STEELS AND ALLOYS WITH OXIDE CERAMICS AT MAKING ARTICLES Russian patent published in 2005 - IPC

Abstract RU 2251469 C1

FIELD: machine engineering, namely manufacture of three-dimensional cermet articles, possibly in stomatology for making dentures.

SUBSTANCE: process comprises steps of applying ceramic mass with thickness more than 50 micrometers onto surface of stainless steel or alloy; performing sintering in air in quasi-homogenous electromagnetic field at presence of electric and magnetic components of SHF electromagnetic irradiation. Frequency range 1 -30 GHz; amplitude of electric field E₀ is in range 400 -1600 V/cm. Amplitude of magnetic field H₀is in range 0.8 - 3.5 A/cm. Maximum temperature of sintering is in range 800 - 1100° C.

EFFECT: enhanced adhesion of materials, possibility for joining materials in atmosphere at standard pressure.
