摘要

"Cermet composition, and method for protecting a metal superfu00eccie exposed to an erosive material.Are provided in which phase cermets ceramic is selected from the group consisting of Cr ~ 23 ~ C ~ 6 ~ Cr ~ 7 ~ C ~ 3 ~ Cr ~ 3 ~ C ~ 2 ~ and mixtures of these.The phase binder is selected from certain alloys in Ni / Cr and certain alloys Fe / Ni / Cr specific. These cermets are used particularly in the protection of surfaces from erosion at high temperatures.
