A two-step, low-temperature thermal chemical vapor deposition (CVD) process, which uses camphor for synthesizing continuous graphene layer on Cu substrate is reported. The growth process was performed at lower temperature (800 °C) using camphor as the source of carbon. A threezone CVD system was used for controlled heating of precursor, in order to obtain uniform graphene layer. As-grown samples were characterized by X-ray diffraction (XRD), Raman spectroscopy and transmission electron microscopy (TEM). The results show the presence of 4–5 layers of graphene. As-grown graphene transferred onto a glass substrate through a polymer-free wet-etching process, demonstrated transmittance ~91% in visible spectra. This process of synthesizing large area, 4–5 layer graphene at reduced temperature represents an energy-efficient method of producing graphene for possible applications in opto-electronic industry.

In this paper, the new high temperature ceramic matrix coating of anti-oxidation for stainless steel was prepared by slurry method. With the research about oxidation resistance of ceramic matrix coating formed on stainless steel, the effect of initial melting temperature, melting temperature range and thermal expansion coefficients of ceramic sintering change on protective properties of high temperature coating prepared at 1250°C is investigated, and then high temperature sintering ceramic with high-performance is gained through optimization. Through the test of TG-DTA and XRD to the coating, study on high temperature oxidation resistance of ceramic coating and the structure changing of the scale with coating from SEM images and photos, it is shown that the ceramic coating has excellent oxidation resistant properties, the weight loss with coating decrease more than 85%.

Wet Synthesis

Silver nanoparticles (Ag-NPs) were prepared by wet synthesis. The Ag-NPs suspension and the copper substrate plate were used for a preparation of substrate-nanoparticle-substrate samples. The sandwich like samples Cu/Ag/Cu were prepared and investigated in-situ at the isothermal external conditions (IEC) and inside apparatus for simultaneous thermal analysis STA409 (DSC). The in-situ results of the electrical resistance were recorded during the Cu/Ag/Cu (IEC) sample preparation and heat treatment. Thermal effects of the Ag-NPs sintering between copper substrates were measured by differential scanning calorimetry (DSC) under different atmospheres. The prepared Cu/Ag/Cu sandwich samples were characterised by means of both optical and electron microscopy. The process of the low temperature sintering inside calorimeter of the Ag-NPs was monitored using both thermogravimetry (TG) and DSC technique under inert gas and under synthetic air. The exothermic heat effect of nanosilver sintering was evaluated.

Nickel Based Alloy

The SiO2-BaO-CaO-MgO-ZnO glass-ceramic (GC) coating was prepared on the surface of the nickel based alloy GH140 by slurry spraying technique. Morphology, phase and elemental composition of the glass-ceramic before or after isothermal oxidation for 96h at 1000°C were investigated by SEM, XRD and EDX,. Results showed that the glass-ceramic was mainly composed of BaSiO4 and MgCrO4, and the amount of them both increased after being oxidized for 96h. Compared with bare GH140, GC/GH140 presented a pretty good antioxidant capacity. Before oxidation, white elongated crystals were homogeneously distributed in the glass phases, and a thin transitional layer had already been formed between glass-ceramic and substrate. During the oxidation process, the surface morphology of GC/GH140 became coarse, and small black Si-rich crystals appeared and well-distributed in the coating. Meanwhile, Cr and Ti in the substrate diffused to the interface, which lead to the formation of an oxide-rich interface that protected the substrate from further oxidation.

Electroless Ni

In this paper，electroless Ni-P plating on copper substrate at 50 °C in ultrasonic field was carried out. The frequency of ultrasonic waves was 40 kHz. The effect of ultrasonic on the composition, plating rate and morphology of Ni-P deposite was investigated at the ultrasonic power of 40, 70 and 100 W. The experimental results showed Ni-P deposit could not be obtained without ultrasonic field at 50 °C. The content of nickel and the thickness of Ni-P deposit increased with the ultrasonic waves power increase. Ultrasonic irradiation power remarkably refines the nodule size of Ni-P particles. The collapse of cavities in solution seems to suppress the Z-direction growth of the nodule.
