Processing and microstructural development of wear protection coatings based in the Fe-Cr-C system

本项目将首次对碳化铬覆层的冶金工艺进行科学研究。由于碳化铬覆盖层在自然资源开采中无处不在，因此该主题与加拿大经济密切相关。对质量和性能的不断增长的需求导致了一些产品被接受的问题，并且没有足够的基础知识来做出关于过程改进的有效决策。碳化铬覆盖层的物理复杂性已经超出了工业能够独立解决的范围，技术上是基于借鉴白口铸铁的启发而制定的，这两种铸铁的化学成分有些相似，但加工问题却截然不同。这项建议的结果将使加拿大制造商能够了解影响质量和性能的覆盖层的特定问题，并了解可以控制的内容以及如何在经济限制下获得世界一流的产品。

This project will look for the first time in a scientific way the metallurgy of chrome carbide overlays. The topic is of much relevance to the Canadian economy because chrome carbide overlays are ubiquitous in the exploitation of natural resources. Increasing demands for quality and performance have resulted in problems in getting some product accepted, and without enough understanding of the fundamentals to make effective decisions about process improvement. The physical complexity of chrome carbide overlays has been beyond what industry could tackle independently, and technical have been made based on borrowed heuristics from white cast iron, which shares somewhat similar chemistry, but very different processing issues. The results of this proposal will enable Canadian manufacturers to understand the particular issues of overlays that affect quality and performance, and to know what can be controlled and how to obtain a world class product within economic constraints.
