Abstract: A valve for use in an internal combustion engine is disclosed. The valve includes a stem connected to a fillet disposed between the stem and a seat face. A port receives the stem and accommodates a seat insert that engages the seat face when the valve is in a closed position. The seat insert is fabricated from a non-cobalt-based alloy or an iron-based alloy and the seat face is coated with a cobalt-based alloy or a nickel-based alloy. The coating may be applied using a thermal spray process, such as HVOF.
