Powder
metallurgy brake block has both the friction coefficient suffer no effect on
weather as casting iron brake block does, but also has the friction coefficient
do not change with the train speed same as organic synthetic brake block does.
And the wear resistance and thermal conductivity are all well. The high-speed
train, high-power locomotives and French TGV high speed trains are all used
this kind of brake block in Sweden, Canada and other countries. And they have
achieved certain braking effect. But powder metallurgy brake block has great abrasion on wheel. Its cost is higher than
cast iron brake block and organic synthesis, thus make it difficult to use a
lot.
