Abstract:
PCT No. PCT/DE89/00220 Sec. 371 Date Dec. 20, 1989 Sec. 102(e) Date Dec. 20, 1989 PCT Filed Apr. 13, 1989 PCT Pub. No. WO89/10423 PCT Pub. Date Nov. 2, 1989.In a laminate material or a laminate workpiece with a functional layer affixed to one surface of a solid backing layer, the functional layer consisting of components which are not soluble in one another, thus normally forming a heterogeneous structure, a finely dispersed distribution of the undissolved components in a matrix of the functional layer is created, due to the fact that the components forming the functional layer are affixed to the backing layer as a fine powder material in the form of a powder mixture or agglomerated powder or predispersed powder formed through air plasma spraying. Thereby the backing layer itself contains a partial layer to be coated having a heterogeneous structure or a crystalline structure, for instance a lead bronze layer or a lead tin bronze layer. This partial layer is created in a surface region by the action of the plasma flame in a strictly defined zone down to a certain depth, for instance 20 to 200 mu m, where it is continuously melted down while the functional layer is built up from fine powder material over this molten bath and the area surrounding it. Through an immediately following cooling with high cooling rate, the surface regions of the partial layer and the functional layer are frozen in a dispersed to a finely dispersed form. Optionally, between the partial layer and the functional layer, an intermediate adhesive layer can be provided, preferably through air plasma spraying, in order to achieve this way the desired structure change in the surface region of the backing layer.
