    摘要: The present invention relates to a process for the laminar bonding of materials using a carrier material and at least one electroconductive and possibly compressed powder coat, or an electroconductive powder which is compressed to form a flat moulded article, whereby the carrier material and the powder coat, or the powder-based moulded article are subjected briefly to a magnetic alternating field in the frequency range of ca. 10 kHz to 120 MHz in order to generate in the powder coat or the powder-based moulded article an induction current of such energy density that the points of contact of the powder particles among themselves and if a carrier material is used, also their points of contact with the carrier material are fused together at a temperature above the sintering temperature.
