Microstructure surface

Most of the surface is covered with a black corrosion product that is thicker in relatively low-flow areas near the hub. This layer of soft corrosion product can be shaved from corroded surfaces. Microstructural examinations revealed flakes of graphite embedded in iron oxide near the surfaces.

Consideration of physico-chemical phenomena occurring upon glueing Investigations of living tissues, estimation of surface energy, surface microstructure at different size levels, the presence of functional groups capable of chemical interaction are the main points characteristic for the physico-chemical approach. 

McCreery and co-workers have investigated the redox reactions for several redox analytes at glassy carbon electrodes, and have summarized the categorization of redox systems according to the effects of surface modification on electrode kinetics [1-3]. These redox analytes in the present study are known to be sensitive or insensitive to the electronic properties, surface microstructure, and surface termination of the carbon electrodes.

The Brunaurer Emmett Teller specific surface area (BET SSA) of carbon black is influenced by the size, the porosity, and the surface microstructure of the primary particles. Surface heterogeneities given by graphitic planes at the surface, amorphous carbon, crystallite edges, and slit-shaped cavities representing adsorption sites of different energies describe the surface microstructure.

SEM photographs of the surfaces of the sintered samples are shown in Fig. 4 (A). The surface microstructure reveals uniform and fine grain growth about 2-3 pm. No pores were observed on the surface of the sample, but there were some pores from the fracture surface of the sample, as shown in Fig. 4 (C). The sintered density is 6.6 g/cm, which is over 95% of the theoretical value. The residual pores may be partly attributed to the agglomerates in the source powders that lowered the sinterability of the green bodies. It can also be seen that there are no great changes between the pellets sintered in air before and after heat treatment at 750°C for 5h in H2. This result is in aecordance with that of XRD. It confirms that the samples are chemically stable in H2 atmosphere at least below 750°C. 

An important future objective in the present field of research evidently concerns surface characterization during and after the anodic and open-circuit processes under consideration, not only as far as the surface composition is concerned, but also from the viewpoint of the surface microstructure and defect structure. Recently developed in-situ techniques such as FTIR, photocurrent imaging by laser scanning and STM may constitute excellent tools for this purpose.
