Influence of B4C addition on the tribological properties of bronze matrix brake pad materials

#Hotpressed bronze #brake pads reinforced with >3 wt% B₄C show improved hardness, friction stability, #WearResistance, and FSC, with 9 wt% B₄C offering optimal friction performance and 6–12 wt% meeting high-performance braking requirements.
