Coke drums are critical components for high efficiency extraction of fuels from oil sands. The mechanical integrity of coke drums contributes to plant safety, extended service life, and production of greener energy. Suncor Oil Sands and In Situ has experienced recurring cases in which jagged cracking was discovered in the coke drum cladding where maintenance repair had been applied. A failure analysis has been conducted, but a root cause has not been identified, and the cracking appears to be more than a "failure analysis" case. This Engage project aims to investigate the metallurgy of the dissimilar cladding/repair alloy system, to understand the mechanism of cracking, and to develop research strategies for improved overlay design and practice.

焦炭塔是从油砂中高效提取燃料的关键部件。焦炭塔的机械完整性有助于工厂安全、延长使用寿命和生产更绿色的能源。森科尔油砂和原位经历了反复出现的情况下，锯齿状裂纹被发现在焦炭塔包层的维护维修已申请。已经进行了失效分析，但尚未确定根本原因，开裂似乎不仅仅是“失效分析”案例。该Engage项目旨在研究异种覆层/修复合金系统的冶金学，了解开裂的机理，并制定改进覆层设计和实践的研究策略。
