| Abstract: |
| Through the combination of theoretical calculations of thermodynamics and experiment a reasonable coating system has been selected. Ni-base alloy composite coating has been produced on Cu alloy surface by C02 flow transverse laser. Ceramic particle reinforced phase has been in-situ syntheszed. Through calculating of the laser cladding coating reacting system' s AGT and XRD analysis, the system of TiB reinforced particle can be in-situ synthesis. By using OM, SEM and microhardness tester show that cladding and the matrix take on fine combine interface. The dendrites in the coating dispersing homogeneously are very thin. The microhardness of the coating increases prominently comparing to the matrix and the average value is about 3 times higher than the copper substrate. |
