Methyl Orange Dye

The adsorption of methyl orange dye from aqueous solution was investigated with active carbon powder as sorbents. Effects of selected factors were studied through the use of L16 (44) orthogonal experiment for the optimal parameter. The results demonstrated that the orders of their influences were contact time > initial dye concentration > the dosage of active carbon powder > pH. It was then concluded that contact time must be given priority in removing methyl orange dye from wastewater. Under the optimum conditions (the dosage 10g, time70min, initial dye concentration 35mg/L, pH7), The active carbon powder possessed good adsorption capacity to methyl orange which the removal efficiency could reached 95.96%.

Hydrogen Peroxide Oxidation

Treatment of deinking wastewater with neutralization, activated carbon, and hydrogen peroxide oxidation is investigated. Discusses the various factors of the neutralization experiment and catalytic experiment on the influence of the experimental results. The results show that for the 20mL deinking wastewater, first neutralize it to pH=4 with dilute sulfuric acid, then the mass fraction of 0.8mLH2O2 (mass fraction of 30%) and 0.8g active carbon powder in oxidative 19min under conditions of pH=3 with an optimum addition of 0.8mg H2O2 (30%) as well as 0.8g active carbon powder, the CODcr can be reduced from 31000mg/L to 2300 mg/L, and the color unit can be reduced from 15000 to 0 after treatment ,its CODcr and color unit decrease significantly and the removal rates reach 90% and 100% respectively.

Hardened Surface

The electron beam cladding of vanadium and graphite powder mixture with additions of the flux agents on thick steel workpieces was implemented using the “ELV-6” electron accelerator. Structural and tribological investigations of the hardened surface were carried out. It was shown that cladding of vanadium-carbon powder mixtures by high-power electron beam injected to the atmosphere led to formation of high quality coatings. The highest microhardness level of cladded layer reached 12 GPa. Thickness of the surface layer was in the range 2.5-3.4 mm. Concentration of hard vanadium carbide particles increased with decrease of layer thickness which resulted in growing the wear resistance level of modified material.

Sintering Method

TiC/Ti3AlC2 composites were successfully prepared by hot-pressing sintering method from the elemental powder mixtures of Ti, Al and TiC. A possible reaction mechanism was investigated by XRD. The density, Vickers hardness, flexural strength, and fracture toughness of the TiC/Ti3AlC2 composites were also measured. At 660 °C, Al melted and reacted with Ti to form TiAl3. At 900 °C, TiAl3 reacted with TiC and Ti to form Ti2AlC. At 1100 °C, Ti2AlC reacted with TiC to form Ti3AlC2. Increasing the sintering temperature, the content of Ti3AlC2 increased. The TiC/Ti3AlC2 composites had excellent performance after sintered at 1100 °C, the density, Vickers hardness, flexural strength and fracture toughness of the composite were 4.35 g/cm3, 4.72 GPa, 566 MPa and 6.18 MPa·m1/2, respectively.
