Electrophoretic deposition is a good method in the preparation of hydroxyapatite/bioglass graded coatings. Its processing parameters are easy to be operated. As it is nonbeeline process, it can be used in the deposition of complex shape and porous surface. This paper reviewed the advancement of the graded coatings in recent years, concluded the principles, characters, steps of electrophoretic deposition of bioceramic coatings and analyzed influencing factors in detail, such as granularity of suspension, aging of suspension, dispersion media, PH of suspension, electricity, voltage, deposition time, pretreatment of substrate and sintering. The foreground of hydroxyapatite/bioglass graded coatings is expected.

Otsu’S Method

The traditional Otsu threshold algorithm is not a good method for processing the real images because of complex shape and unbalanced distribution. To solve this problem, the paper uses the thinking of Otsu’s method for reference, introduces a threshold segmentation algorithm based on histogram statistical property. In addition, the paper draws a comparison between the new algorithm and Otsu’s algorithm. Experimental results show that the new algorithm can get better segmentation effect than that of Otsu’s method when the gray-level distribution of the background follows normal distribution approximatively, and the target region is less than the background region.

Transfer Pressure

In this paper a pseudo-HP process, which uses solid powder to transfer pressure to prepare complex shape articles, was adopted to prepare 2D C/SiC composites. Nano-SiC powder was used to lower the sintering temperature, thus decreasing the damage to carbon fibers. The optimum processing parameters are as follows: sintering temperature 1850°C, holding time 60min, sintering pressure 10MPa. The maximum strength is over 300MPa, and toughness is around 8MPa·m1/2. BN powder is more lubricous than carbon powder, and thus is more convenient for demoulding and pressure transferring. Precursor Infiltration and Pyrolysis (PIP) was used to further densify the composites after HP process, and strength and toughness of the samples were slightly enhanced.

The electrophoretic deposition of TiO2 iron oxide nanocrystal monolayers from stable, mixed colloidal suspensions by electrophoretic deposition using non polar solvents is reported. The selective deposition of TiO2 was accomplished by controlling the mobility of the nanocrystals and the voltage during electrophoretic deposition. The effect of the electrophoretic deposition processing parameters (voltage and particle mobility) on the promotion and suppression of nanocrystal deposition was investigated.

The application of electrophoretic deposition (EPD) technique for deposition of thick and thin film deposition has been extended not only on to electrically conducting materials but also to non-conducting material. The review encompasses the fundamental aspects of EPD technique and specific factors influencing the EPD process on non-conducting substrate. Important EPD processing parameters, during EPD on non-conducting substrate discussed are types of substrate, counter-electrode substrate and substrate additive. The parameters were discussed based on the up-to-date comprehensive overview of the current research progress in the field of EPD on non-conducting material.

Wood Polymer Composite

Inspired from the natural porous structure of wood, a novel wood-polymer composite combining both advantages of wood with high strength-to-weight ratio as a natural renewable resource and polymer as a reinforcer was manufactured by synthesis of terpolymer of methyl methacrylate (MMA), Styrene (St) and Vinyl Acetate (VAc) inside wood. The three kinds of monomers with a few of 2,2'- azobisisobutyronitrile (AIBN) as an initiator, as well as some additives were first impregnated into wood porous structure under a pressure condition, and then initiated for terpolymerization through a catalyst-thermal treatment. The impregnating conditions containing pressure value and pressure time, and polymerizing crafts including heating temperature and heating time, as well as additive content were confirmed according to rate of monomer loading and rate of polymer loading inside wood. Results indicate that among these influencing factors, pressure and temperature were the significant influencing factors; and the rate of monomer loading and rate of polymer loading linearly positive correlated to them, respectively. SEM observation shows that the terpolymer fully filled in wood porous structure under the optimum manufacturing craft.
