Low-friction material for bearing surfaces

The material consists of a sintered, high-strength metal structure satd. with an intermetallic, homogeneous compd. (e.g. SbCd, Cd8Cu5) or heterogeneous compound e.g. Cd8Cu5/Cd3Cu4 eutectic. Spec. a low friction and wear coefficient is obtained by sintering the material and incorporating insoluble me...

Beschreibung
Zusammenfassung:	The material consists of a sintered, high-strength metal structure satd. with an intermetallic, homogeneous compd. (e.g. SbCd, Cd8Cu5) or heterogeneous compound e.g. Cd8Cu5/Cd3Cu4 eutectic. Spec. a low friction and wear coefficient is obtained by sintering the material and incorporating insoluble metals (e.g. Cd, Pb, Bi, Na, Ca) and soluble metals (e.g. Cu, Zn, Ni) in the complementary material (steel). The material is used for cross-heads in plunger-die casting machines.
