【摘要】 研究开发了具有优良工艺性能的高温合金炉管离心铸造专用涂料，与进口的ＫＯＴＥ２１３．１ 型离心铸造涂料进行了对比试验，结果表明：研制的专用涂料具有优良的工艺性能，各项技术性能指标达到或超过ＫＯＴＥ２１３．１ 涂料，可在喷涂条件下形成高质量的特种涂层，生产出可与进口炉管媲美的优质高温承压合金炉管．还对ＰＨ 涂层（表面具有均匀坑孔的特种涂层） 的形成机制进行了探讨，提出了高质量ＰＨ 涂层的结构模型与专用涂料的设计思想更多还原

【Abstract】 On Possessing excellent technical properties, special coating used in the centrifugal casting of furnace tubes made of high temperature alloys had been studied and developed. A series of contrast tests were made between the new coating and the imported kote 213.1 type coating. The results showed that its technical performance indexes had reached or exceeded that of kote 213.1 type coating. It can form high quality PH coat (a special coat with uniformly distributed pit holes on it) under spray-coating condition and produce top quality furnace tubes made of high temperature alloy. In this paper the formation mechanism of the PH coat was also discussed, a structure model of excellent PH coat and the related coating design idea was proposed.更多还原
