Sliding wear is related to asperity-to-asperity contact of two counter surfaces, which are in relative motion against each other. The effective wear from the specimen surface is due to the combined effect of a number of factors. An increase in the applied load leads to increase in penetration of hard asperities of the counter surface to the softer pin surface, increase in micro cracking tendency of the subsurface and also increase in the deformation and fracture of asperities of the softer surface. In general, composites offer superior wear resistance as compared to the alloy irrespective of applied load and B4C particles volume fraction. This is primarily due to the presence of the hard dispersoid which protects the matrix from severe contact with the counter surfaces, and thus results in less wear, lower coefficient friction and temperature rise in composite as compared to that in the alloy. The worn surfaces of all specimens were covered with grooves parallel to the sliding direction and some plastic deformations. These grooves are typical features associated with abrasive wear, in which hard asperities on the steel counter face or hard particles between the pin and disc, plough or cut into the pin cause wear by the removal of the material. Plastic deformation, material smearing, cavities and craters imply adhesive wear.

Inhibition efficiency increases as inhibitor concentration increases. A good correlation was observed between the potentiodynamic studies and electrochemical impedance spectroscopy with electrochemical noise measurements. Hence, it seems that the electrochemical noise (EN) method can be applied as a complementary quantitative technique to study the corrosion behavior of inhibitors. The effect of inhibitor concentration on the interpretation of noise resistance and spectral noise impedance was evaluated. Furthermore, quantum chemical calculations were employed to provide further insight into the mechanism of inhibition by DAT. It was shown that the adsorption of inhibitors on the AA1005 surface takes place through both physical and chemical adsorption. The best fit to the experimental data was obtained using Langmuir adsorption isotherm.
