Streszczenie / Summary:

This paper describes results of a repair process of crankshaft pulley hub made of low-carbon
steel using laser cladding method. Widely used Co-based alloy powder (Stellite 6) was applied
as cladding material. After laser cladding process crankshaft pulley hub has been subjected to
grinding to nominal size. Non-destructive testing (dye penetrant inspection) as well as microscopic
and chemical composition examination of surface layer and substrate were performed on
the cross-section of a control specimen, cut from pulley hub. Produced layer was non-porous
and metallurgically bonded with steel substrate. On the cladding weld a much higher microhardness
relatively to substrate material has been measured.
