| Abstract: | Compatible metallic cam and shaft made form 45 were connected by friction welding.The microstructure and properties in welded joint were analyzed and researched.Together with the reason of lower strength and fracture toughness were investigated to cam shaft made by heat forging.The excellences of the friction welding and joint formation were illustrated.The optimal welding and heat treatment parameters were afforded for friction welded joint. |
| Keywords: | cam shaft friction welding welding joint spheroidize annealing |
