Improvement of wear resistance for engine valve: introducing cold upsetting treatment on valve seating face

This study presents a new surface strengthening technique (cold upsetting manufacturing process) for engine valve seating face (VSF). The properties of the Ni30 superalloy VSF were characterized before and after cold upsetting. Compared to the solution-aging treatment (SAT) valve, the solution-cold...
