Engine valves

Engine valves

Modern combustion engines put high levels of thermal and mechanical stress on valve components. An increasingly viable way to improve the thermal and abrasive wear behaviour of engine valves is surface engineering.

Powder metallurgy (PM) surface coated engine valve components offer outstanding wear resistance and high heat resistance, which ensures excellent functionality and reduced maintenance costs.

Choosing Höganäs’ iron base powder for surface coating of engine valves, you can ensure functionality at an attractive price. With extensive experience from use of different PTA equipment, we can actively support you in optimising the manufacturing process.



Benefits of Höganäs’ solution for PM surface coated engine valves:

  • Heat resistance to withstand hot abrasive wear
  • Good crack resistance
  • Corrosion resistance to withstand engine environment
  • Mechanical and welding properties comparable to cobalt 6 & 12 type materials
