Joining of Metal to Ceramic Plate Using Super-Spread Wetting

Metal-ceramic joining by laser

Within the scope of increase in cutting tools efficiency, a CW CO;! laser beam has been used for butt welding sintered tips containing cobalt and tungsten carbide to a medium carbon steel core. After optimization of the laser processing conditions, full penetrating, sound and homogeneous welds are observed. Hardness is found to be nearly constant across the entire weld bead cross-section. Micro...

Ceramic/metal joining for structures and materials

The paper presents a discussion of the various types of ceramic joining within a conceptual framework based on the fundamentals of wetting, adhesion, and the thermodynamics of interfacial reactions. Examples are given of solid state diffusion bonding of Pt to alumina and brazing of AlN. Most ceramic-metal bonding is conducted at high temperatures, where chemical reaction is to be expected. The ...

Ceramic-Metal Joining Using Active Filler Alloy-An In-Depth Electron Microscopic Study

joining of al-foam to plate in sandwich structures

structural sandwich beams are widely used because of their high specific stiffness and strength, noise reduction, thermal insulation and impact energy absorption characteristics. conventional manufacturing method of composite sandwich structures is completed by a separate adhesive joining stage by which the composite faces are joined to the core. in this investigation, liquid phase sintering in...
