Polycrystalline Y2O3 thin films have been prepared by radio frequency (RF) reactive sputtering. The topographies of Y2O3 films were shown by AFM. The XPS measurement has found the interfacial silicates and the amorphous silicon sub-oxide (SiOx) interfacial layer which is also indicated by the FTIR investigation. The i…
Hydrogen in the steel wall can cause hydrogen embrittlement of the wall material and thereby change the carrying capacity of the vessel. A theoretical model of hydrogen diffusion in the steel wall of a high pressure vessel was established and the formula of hydrogen content in the steel wall was deduced. Based on the…
In this paper, a kind of titanium-doped silicone prepolymer(TDS) was modified by hydroxyl-terminated saturated polyester (HTSP) by condensation polymerization. By Fourier Transform Infrared Spectroscopy (FTIR) the reaction of ethoxy groups of the TDS prepolymer with hydroxyl groups of the HTSP during condensation poly…
Activators generated by electron transfer for atom transfer radical polymerization (AGET ATRP) of methyl methacrylate (MMA) on silica nanoparticles were conducted to create controllable shell on silica surfaces. SiO2–Br, the macroinitiator, was prepared by the reaction of amido groups previously indroduced on silica w…
Single factor method was used to investigate the effects of the main technical parameters ,which was on the Pd deposition rate in electroless Pd plating process. The kinetic equation of palladium deposition was established. When the concentration of EDTA-2Na was less than 6g/L，V= 0.783 CA1.00784 CB0.15225 Cc-0.3373 CD…
Nanostructured ZrO2 was prepared successfully by mechanically activated solid state reaction. The structural and microstructural of products were monitored using X-ray powder diffraction (XRD), transmission electron microscopy (TEM). The effects of ball milling speed and calcined temperature on products were monitored…
We have studied the anodization behavior of an Al film electrodeposited on the 316L stainless steel (316L SS) substrate and demonstrated an effective approach to fabricate the micro-cavities on the conducting substrate through anodic aluminum oxide (AAO) template. The morphologies and composition of the electroplating…
In-mold coating (IMC) of plastic parts is a promising coating process in automotive and consumer products industry. An IMC material, such as carbon black suspension, can potentially be used as a top coat or paint. IMC is performed by injecting a reactive liquid polymer onto a part’s surface in the end of the forming p…
The glass samples of SiO2-Al2O3-CdO-Li2O-K2O-Na2O with different Nd3+-doped concentration by high - temperature solid-state reaction method were fabricated and the absorption spectrums as well as down-conversion fluorescence spectrums were tested. The experiments confirmed that a strong fluorescence emission at the wa…
A series of experiments was performed on studying the dynamic heat and moisture transferring procedure and evaluating heat-moisture comfort properties of functional moisture transported and dry-fast fiber in wearing conditions that produce continued sweat. Experiments were performed in two different environmental cond…
In this paper, octadecylamine (ODA), dimethyl oxime and bromogeramine are selected to complex as a filming amine (FA). Static metal hanging slice test at low temperature is used to study the inhibition performances of the FA. And the influence of the ratio for each component in FA to the properties of the film is stud…
Mg(OH)2 is a kind of inorganic fire retardant additive with many excellent properties. In this paper, taking MgSO4 as magnesium source and mixed alkali solution of NaOH and ammonia water as precipitant, flaky Mg(OH)2 powders were synthesized via precipitation method. The fire retardancies of product were tested throug…
The starch is oxidized to dialdehyde starch by sodium periodate and condensed with urea to generate shrimp feed adhesive. The experimental result shows: Blend 38g starch to 150ml H2O, concoct 15g sodium periodate to PH 1~1.5, heat it for 2 hours within 35～40°C, flush it 4 times and filter it to obtain dialdehyde starc…
Li3V2(PO4)3/C has been synthesized by a simple one-step carbothermal reduction technology using LiH2PO4, V2O5 as the raw materials and sucrose as carbon source. X-ray diffraction (XRD) and scanning electron microscope (SEM) measurements showed that Li3V2(PO4)3/C synthesized by one-step carbothermal reduction had monoc…
ZnO films were deposited on nanostructured Al (n-Al) /glass substrate by RF magnetron sputtering. The results shows that the relation (I (002) /I (100) ≈ I annealed (002)/I annealed (100) ≈1.1) shows the rough n-Al surface is suitable for the growth of a-axis orientation. Meanwhile, the influences of substrate roughne…
Stationary seal ring, the mainly units of mechanical seal, its anti-lacking function mostly depends on the material performances. For enhanced stationary seal ring’s thermal conductivity, self-lubrication and strength, in this paper authors prepared a kind of composite material with reticular formation that is foam Ni…
