Title: Powder metal component impregnated with ceria and/or yttria and method for manufacturing the same
Inventor: DANIS CHRISTOPHERSON JR
IPC: B22F3/24
Filed: 2017-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a porous powder metal component that enables continuous formation of a protective oxide film.SOLUTION: The powder metal component is made of compacted and sintered powder metal particles 13 such as a chromium-containing ferrous-based metal and is porous. After sintering, pores 16 are impregnated with a relatively smaller particles 14 of ceria and/or yttria. Then, the component is heat-treated and the presence of the impregnated ceria and/or yttria 14 serves as a nucleation site for the formation of a desirable oxide, such as chromium oxide, on the surface thereof. The impregnated particles 14 which lie below a protective oxide layer 18 remain available throughout the life of the component in the event the original oxide layer becomes worn or damaged. In the thus-produced porous powder metal component, a regenerated protective oxide 18 is formed in such regions due to the presence of the impregnated particles 14.SELECTED DRAWING: Figure 2
