Abstract:A powder metallurgy material is introduced after a brief analysis of the wear mechanism of the valve seat insert.Such a material contains a hard phase and solid lubricant in a heat-resistant base.After making comparisons through experimentation,it is proven that the material has excellent high temperature strength,high wear resistance,good corrosion resistance and thus is suitable for use in lead-free gasoline engine.
Keywords:valve  seat  insert  powder  metallurgy  material  for  valve  seat  insert  hard  phase  solid  lubricant  lead-free  gasoline
