Composite adhesive joints of hardmetals with steel

Newest developments in the field of gluing and processing of plastics permit obtaining adhesive materials with profitable properties: high mechanical parameters, increased thermal conductivity, low electrical resistivity, increased rigidity, limited residual stresses or reduced creep [1] and [2]. This is possible by composite structure of adhesives, i.e. binders enriched with filling materials – additional phases of different kind, grain size and fraction. In the paper, effect of reinforcing adhesive materials with continuous and powdery fillers on shear strength of adhesive joints is discussed. Presented are also results of electron microscopy examinations and EDX analysis.
