| Abstract: |
| All kinds of mould and dies are often failure due to be wore, scrathed and corrosioned after being used for a while. And they would become waste steel because of surface local failure , which resulted in a great amount of resoure waste. However, some of failure mould and dies could be repaired by corrosponding surface treatment. Thus some kinds of surface technologies used to repair failure mould and dies were described, including build-up welding, thermal spray welding, brush electric-plating, laser cladding and electric spark. Their characteristics and applications were also involved in. It is indicated that tools life would be well prolonged after failure mould and die were repaired. In order to obtain optimal properties, appropriate technologies should be chosen according to surface specific failure. |
