| Abstract: |
| Repair Weldng of cast iron parts is a saving project which has great difficu1ties in technology and better economic effect. A methord is studied in the paper which the defect of cast iron parts was repaired by the powder flame spraying welding. A series of spray materials was developed and effect of spray material types and processing parameters on the melting points of the materials. Boading strenth hardness of spray welded layer and bending fatigue behavor are investigated. |
