Sliding wear behavior of in situ Cu-TiB 2 nanocomposites fabricated by reaction of pure titanium and copper-boron melts were investigated on a pin-on-disk wear tester under dry sliding conditions, rubbing against medium carbon steel disk at sliding speeds range from 0.089 to 0.445ms -1 and at loads between 20 and 140N. The hardness, yield strength and wear resistance of the in...
A copper matrix composite reinforced by in situ TiB 2 nanoparticle was prepared by reactions of B 2 O 3 , carbon and titanium in copper-titanium melt. The microstructure and mechanical and electrical properties of the as-drawn in situ composite were investigated. The results showed that the in situ-formed TiB 2 particles, which had a size of about 50 nm, exhibited a...
