HEAT PROOF BIMETALLIC INSERT Russian patent published in 2008 - IPC B32B7/02 B32B7/04 B23K20/08

Abstract RU 2318670 C2

FIELD: metallurgy.

SUBSTANCE: insert comprises two metallic members that have different coefficients of thermal expansion, are provided with projections, and are welded. The projections of one of the members are made of a continuous grid of intersecting strips. The projections of the other member are the cells of the grid. The section of the projections is shaped into a trapezium. A thin metallic layer can be mounted over the contact surface.

EFFECT: enhanced strength.
