| Abstract: | Fe based composite cladding layer was prepared on high manganese steel substrate by laser cladding
technology under different laser power. The effects of different laser power on the morphology of TiC in the
cladding layer and the properties of the cladding layer were studied. The test results showed that the components
of the cladding layer include austenite and TiC. With the increase of laser power, the TiC precipitates changed
from a single granular to a combination of plum blossom, fern and granular, the grain size increases, and the
hardness and wear resistance of the cladding layer were gradually improved |

| Keywords: | Laser cladding Fe based composite cladding layer Microstructure Wear resistance |
