| Abstract: | Laser claddeing Fe- based self- fluxing alloy/cerarnie TiC composite coatings on 20 steel surface byusing a high power CO2 laser has been fabricated. By analysing microstructure .morphology and chemical compositionsof the laser remelted layer and determining it's hardness and anti-abrasion, it is indicated that under appropriate pro-cessing parameters,a homogeneous and non - porous Fe- based alloy/ceramic TiC layer is obtained. |
