ABSTRACT:
The object comprises a glass-metal film (1) with a metal matrix (2) which has solidified in an at least partly glass-like form and which may comprise hard particles (3, 3a) in the form of primary precipitates from the molten mass. The glass-metal film (1) is provided on at least one side (4) with a top layer (5) comprising a hard material which is harder than the glass-metal film (1). The top layer (5) may be formed by a base layer (7) with embedded hard material particles (8), e.g. of diamond or cubic boron nitride, or by a homogeneous hard material, e.g. diamond-like carbon. The result is a surface quality which can be separately influenced by the composition of the alloy of the glass-metal film (1). The object may be formed either as a parting tool or as a structural part with special wear and/or sliding properties.
