RE: friction properties
Chrmium as a high temperature oxidation and corrosion resistance coating material provides protection below 1000C, and for higher temperature wear resistance Al provides better protection.
For high temperature wear resistance properties of Stellites and Ni-base materials, please check with my two following papers
1.ITSC-95,Kobe, Japan,vol2,proceedings of symposium,p31-34
2.Microstructural Science,vol19,ASM-IMS conf. on envoronmental degradation of materials, Monterey,1992,p477-504
or in concise form in my first book.
