Cast iron brake blocks: Part III. The effect of phosphorus content on friction and wear characteristics using a simulated carriage axle load (TN-MS-12)

Full scale tests have been carried out on the brake dynamometer at BSC (SPT) Rotherham to compare the friction and wear characteristics of brake blocks with widely differing phosphorus contents. Blocks were manufactured with eight phosphorus levels (between 0.05% and 7%). The experimental blocks were assessed under emergency stop conditions...
