| 中文摘要: |
| 各种模具因为反复使用之后均会存在不同程度的磨损，有时存在刮伤、腐蚀，往往因局部表面失效而弃之，从而造成极大的资源浪费。为此，可以针对不同的模具失效方式和相应的表面处理技术对其失效模具进行修复再利用。基于此目的，综合介绍了目前用于模具修复的几种表面技术及其特点和应用，包括堆焊修复技术、热喷焊修复技术、电刷镀修复技术、激光熔覆修复技术和电火花修复技术。指出应用表面技术修复失效的模具，可显著延长其使用寿命，且不同的失效形式需选用相应的修复方法，才能使修复后的模具性能达到最佳。 |
| 英文摘要: |
| 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. |
