Abstract

The invention discloses a combined metal solid armature for electromagnetic emission and a manufacturing method thereof. The combined metal solid armature is formed by combining a pure copper block (3), a pure aluminum block (2) and a commercial pure titanium block (6) into a whole in an interference fit mode through duralumin double-dovetail-groove connecting keys I and II (4 and 4'), wherein the pure copper block (3), the pure aluminum block (2) and the commercial pure titanium block (6) are similar in shape, the proportion of the contact area between the pure copper block (3) and an electromagnetic emission track to the contact area between the pure aluminum block (2) and the electromagnetic emission track to the contact area between the commercial pure titanium block (6) and the electromagnetic emission track is 1:2:1.3, and the conductivity of the pure copper block (3), the conductivity of the pure aluminum block (2) and the conductivity of the commercial pure titanium block (6) are gradually increased. The combined metal solid armature is a C type armature. According to the combined metal solid armature, by the adoption of the segmentation and combination technology, gradient distribution of the conductivity is ingeniously achieved, and the problem that the gradient change of the conductivity of a homogenous material can not be achieved easily or a material with the gradient change of the conductivity can not be prepared easily is solved. Due to the fact that the conductivity is decreased gradually and the strength is improved gradually from the front section to the rear section, redistribution of currents is facilitated, the phenomenon that the currents are excessively accumulated at the single tail portion is relieved, and the thermal ablation resistance and the electromagnetic force resistance of the solid armature are improved.

Description

technical field [0001] The invention relates to a combined metal solid armature for electromagnetic emission and a manufacturing method thereof, which belongs to the technical field of electrical contact materials. Background technique [0002] The solid armature is the key component in the electromagnetic launch device, and it is the carrier of electric current and electromagnetic force. When the pulse current flows through the solid armature, the solid armature is subject to complex physical coupling processes such as electricity, magnetism, heat, and stress, while the current and Joule heat are often concentrated at the tail of the armature and the track contact. Due to the strongly uneven distribution of electricity, magnetism, force, and heat on the solid armature, it often causes strong ablation and fragmentation of the solid armature, which in turn affects the emission efficiency of the solid armature. Aiming at the current skin effect, uneven heat and force distribu...
