【期刊论文】Effect of aging treatment on the electrical sliding wear behavior of Cu-Cr-Zr alloy

The wear behavior of aged Cu-Cr-Zr alloys dry sliding against a brass counterface were investigated on a pin-on-disk wear tester under electric current conditions. The worn surfaces of the aged Cu-Cr-Zr alloys were analyzed by scanning electron microscope (SEM) and energy dispersive X-ray spectrum (EDS). The results indicated that the aging treatments had an effect on the microstructure, hardness and wear resistance of Cu-Cr-Zr alloy. At the constant current density, the wear rate of Cu-Cr-Zr alloy decreased with aging temperature, and reached the minimum at 500℃, then increased with further increasing aging temperature. An appropriate aging treatment may improve the wear resistance of the materials due to the formation of fine, dispersive and coherent precipitates within the matrix. An increase in electrical current resulted in an increase in wear rate of both the Cu-Cr-Zr alloy pin, and the brass disk. Adhesive wear, abrasive wear and arc erosion were the dominant mechanisms during the electrical sliding processes. Compared with commercially used Cu-Ag alloy wire (CTHA110) under the same test conditions, the Cu-Cr-Zr alloy treated at 500℃ for 2 h exhibited much better wear resistance.

【期刊论文】Tribological properties of carbon-nanotube-reinforced copper composites
涂江平, J.P. Tu a, Y.Z.Yanga, L.Y. Wanga, X.C.Mab and X.B. Zhang a

Tribological properties of carbon-nanotube-reinforced copper composites were investigated using a pin-on-disk test rig under dry conditions. The composites containing 4-16 vol% carbon nanotubes (CNTs) were fabricated by a powder-metallurgy technique. The tests were carried out at normal loads between 10 and 50 N, and the effect of volume fraction of CNTs on tribological behavior of the composites was examined. The composites revealed a low coefficient of friction compared with the copper matrix alloy. Due to the effects of the reinforcement and reduced friction, the wear rate of the composites decreased with increasing volume fraction of CNTs at low and intermediate loads. The composites with a high volume fraction of CNTs exhibited high porosity and their wear resistance decreased under high-load conditions.

Adhesion strength and high temperature wear behaviour of ion plating TiN composite coating with electric brush plating Ni-W interlayer deposited on a hot work die steel were investigated using a plate-on-ring test rig. The microstructure and wear characteristics of the coating were analyzed using XRD, TEM, SEM and EDS. The adhesion of the coating to the substrate was determined by scratch test. The results indicated that crystallization and precipitation-hardening in the electric brush plating Ni-W interlayer and formation of interface diffusion layer and duplex composite layer at the interface occurred due to thermal effects during TiN deposition. The Ni-W interlayer could provide an effective support for the TiN coating, thus the adhesion strength and hardness of the TiN composite coating increased significantly. In the temperature range 500-7008C, the TiN composite coating with Ni-W interlayer revealed high wear resistance as compared with the single TiN coating. The coefficient of friction and wear rate of the single TiN coating increased as the temperature increased, while the TiN composite coating exhibited the lowest coefficient of friction and wear rate at 6008C. Abrasive and adhesive wear were the predominant wear mechanisms of the coatings at elevated temperatures.

Ni-P-Carbon nanotube (CNT) composite coatings as well as Ni-P-SiC and Ni-P-graphite coatings were prepared by electroless plating. The tribological properties of these composite coatings were investigated using a ring-on-block test rig under lubricated condition. The Ni-P-CNT composite coatings exhibited not only high wear resistance but also low friction coefficient compared with the Ni-P-SiC and Ni-P-graphite composite coatings. The favorable effects of CNTs on the tribological properties of the electroless coatings are attributed to improved mechanical properties and unique topological structure of the hollow nanotubes. In addition to preventing the rough contact between the two mating metal surfaces, the shorter CNTs can easily slide or roll within the surfaces of friction pairs. Therefore, the wear rate and friction coefficient of Ni-P-CNT composite coatings can be substantially reduced.

【期刊论文】Size and morphology effects of ZnO anode nanomaterials for Zn/Ni secondary batteries

ZnO nanoparticles and nanorods as anode active materials were investigated by charge-discharge cycle measurements. The ZnO nanomaterials with larger specific surface area exhibited higher electrochemical activity than conventional ZnO particles. The discharge capacity delivered by ZnO nanorods exceeded 500 mA hg−1 until the 175th cycle. It also exhibited higher midpoint discharge voltage than conventional ZnO. The morphologies of ZnO had a significant effect on the electrochemical properties of the anodes. In the initial cycles, the morphologies of ZnO did not essentially change due to the extension effect, and the electrochemical performance of the electrodes was relatively stable. With increasing the cycles, according to the texture growth mechanism, the large flaky ZnO parallel to the substrate surface predominated to reduce the electrochemical performance. Due to the intensive extension effect, the growth mode of ZnO nanorods changed. The eventual morphology was erect small flaky ZnO crystals that suppressed the production of Zn dendrite and enhanced the capacity maintenance.

【期刊论文】Microstructure and tribological behavior of a peak aged Cu--Cr-Zr alloy

The friction and wear behavior of peak aged Cu-Cr-Zr alloys dry sliding against a brass counterface were investigated on a pinon-disk wear tester. The microstructure of the aged Cu-Cr-Zr alloy before and after wear tests was analyzed by transmission electron microscopy. The worn surfaces of the Cu-Cr-Zr alloys were studied by scanning electron microscopy and energy dispersive X-ray spectroscopy. The results indicated that an appropriate aging treatment resulted in the formation of fine, dispersive and coherent precipitates in the Cu matrix and thus could improve the hardness and wear resistance of the Cu-Cr-Zr alloy. The wear rate of the aged Cu-Cr-Zr alloy increased monotonically with increase of the normal load. With increasing sliding speed, the wear rate of the peak aged Cu -Cr-Zr alloy decreased initially and then began to increase. After reaching the maximum wear rate at a speed of 0.445ms-1, the wear rate decreased again with further increasing in the sliding speed. Adhesive wear and abrasive wear were the dominant wear mechanisms under unlubricated conditions.

A copper matrix composite reinforced by in situ TiB2nanoparticle was prepared by reactions of B2O3, 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 TiB2 particles, which had a size of about 50 nm, exhibited a homogenous dispersion in the copper matrix. Due to their reinforcement, the tensile strength and hardness of the in situ Cu-TiB2 composite significantly improved. Moreover, the as-drawn in situ composite had a high electrical conductivity.

Spinel LiMn2O4 materials were synthesized via sintering of a precursor which was obtained from the solution of the corresponding metal acetate by a spray-drying method. Following sintering at 600 C for 15h, the spinel LiMn2O4 particles that are formed are fine, narrowly distributed, and well crystallized. The synthesized material has excellent electrochemical properties as a cathode, delivering an initial discharge capacity of 137mA h/g and exhibiting good cycle stability.

The sealed Ni/MH batteries with carbon nanotubes (CNTs) in the positive electrodes were assembled. The overall characteristics of Ni/MH batteries were investigated at different charge-discharge cycles at room temperature. The high-rate discharge performance of the Ni/MH battery was improved by the addition of CNTs in the positive electrode. Under high-rate discharge conditions, the batteries with CNTs added in the positive electrodes exhibited much better cycling stability, higher discharge voltage, and high-rate capability. The increase in internal resistance of the batteries with CNTs was lower than that of the batteries without CNTs during charge-discharge cycles. The addition of 0.5 wt.% CNTs was proved a desired amount to modify the batteries performance at the high discharge rates. Too much CNTs contributed no effect in the improvement of overall performance of the batteries.
