Abstract
The invention discloses a powder metallurgy brake lining friction block for a high-speed train and a preparation method thereof. The friction block comprises a copper-plated backboard and a friction body. A transition layer is further arranged between the copper-plated backboard and the friction body and metallurgically fused completely with the copper-plated backboard and the friction body. The copper-plated backboard is made from a Q345B material through copper plating. The transition layer is formed by mixing metal powder and copper powder and then sintering the mixed metal powder and copper powder. The copper-plated backboard and the friction body are spliced together through the transition layer during sintering. The friction block prepared through the method can overcome the defect that a backboard and a friction body of an existing friction block are low in splicing strength and consequently the backboard and the friction body are separated and prone to falling, and the service life of a powder metallurgy brake lining made of the friction block is prolonged.
