Abstract
This invention relates to sintered ferrous materials. Sintered ferrous materials in accordance with the invention contain at least 50 percent by weight of iron and glass in an amount of not more than 2 percent by weight. The iron can be present as pure iron or as an alloy thereof. The materials can be produced by known powder metallurgical methods, for example by compression in the presence of a lubricant and subsequent heating. The glass generally serves to seal the pores between the particles of the iron-containing powder, and the materials have been found to have low porosity to gases and liquids and increased corrosion resistance compared with similar materials containing no glass. Sintered ferrous materials in accordance with the invention can be used for producing valve seats.
