铸件可见缺陷采用粘接技术修补,是近几年来才应用于生产实践的一项新技术。过去铸件产生的气孔、砂眼、缩松等铸造缺陷长期得不到解决,一个铸件往往加工至半成品乃至成品才发现缺陷而报废。我们把经过机械加工或经过长期运用才发现的用肉眼能看见的铸件缺陷称为可见缺陷;而通过打磨后才能发现的铸件缺陷称为微细铸件缺陷。目前,通过粘接和浸渗已能修补这两种缺陷。

Casting visible defects using adhesive repair technology, in recent years has been applied to the production of a new technology. Casting the past produced stomata, trachoma, shrinkage casting defects such as long-term can not be resolved, a casting is often processed until the semi-finished products and even finished defects were discovered and scrapped. We found that after machining or long-term use found that the naked eye can see the casting defects as visible defects; and grinding can be found only after casting defects known as micro-casting defects. At present, these two defects can be repaired by bonding and impregnation.
