Iron-base sintered alloy for valve seat and its manufacture |
摘要 |
A novel group of iron-base sintered alloys especially suitable for valve seat manufacture having excellent wear resistance and good machinability is provided. The alloy is produced by a combination of specific atomized pre-alloyed powder, iron powder and graphite powder by compacting and sintering processes. Various manufacturing methods with or without infiltration of filler materials into pores in the sintered product to improve wear resistance and machinability are disclosed.
