Abstract:

Metal matrix composites reinforced with dispersed carbide particles have an optimal combination of strength and wear resistance. The composites are used as structural materials, wear-resistant materials and coatings as well as functional materials. Copper matrix composites for electrical purposes are strengthened with particles of refractory compounds (carbides, borides, silicides). They are used to manufacture breaking electrical contacts which have increased resistance to erosion under the electric arc exposure. The highest arc erosion resistance is achieved by composites with a structure, i

Abstract:

In this paper, five kinds of composite materials were prepared by using graphene oxide (or graphene) doped with TiO2. The photocatalytic properties of five kinds of composite materials, pure graphene oxide and pure TiO2 for methyl orange, phenol solution and rhodamine B simulated laboratory wastewater were studied respectively. The experimental results show that the photocatalytic performance of graphene oxide-doped titanium dioxide composites is better than that of graphene oxide-doped titanium dioxide composites. When graphene oxide is doped with titanium dioxide as catalyst, the higher the

The composites were produced with the same phosphor molar concentration. The mixtures were prepared by ultrasound in water, dried in a rotary evaporator, pressed at 600 MPa and vacuum-sintered at 1200 °C for 2 hours. The mixtures were well dispersed by ultrasound and agglomerate-free. The analyses show that titanium particles were coate
