摘要
通过试验,提出了涂层在高温下开裂的原因,是由于涂层与型芯相对热膨胀率的差异引起的;解决措施是尽可能地减少涂层与型芯之间的相对热膨胀率的差异。
The reason of the coating layer cracking at high temperature has been analyzed. And the experimental results indicated that.
1. The reason of cracking of coating layer at high temperature is the difference between the coating layer and core on thermal expansion.
2.The essential method for reducing the tendency of cracking is to reduce the difference in the relative thermal expansion between the coating layer and core as lower as possible.
