Abstract: 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.
