Opis:: The aim of this study was to fabricate 30 wt.% AlB₂/Al-Cu composites using in-situ casting processes and to investigate the corrosion behavior of the composites and of the matrix material in various media. The electrochemical parameters were obtained from potentiodynamic polarization curves. The composites were prepared by liquid reaction of aluminum matrix with boron oxide at 1400°C. The results show that the corrosion resistance of the composite was higher than that of the matrix in selected corrosion media. The anodic corrosion current density values were decreased by reinforcing AlB₂ particles.

Opis:: In internal combustion engines, friction losses caused by piston ring and cylinder liner pair account for approximately 20% of total mechanical friction losses as reported in literature. A reduction in friction between piston ring and cylinder liner pair would therefore result in higher efficiency, lower fuel consumption and reduced emissions. In this study, the effects of different types of fuel which is contaminated to cylinder oil have been tested for investigating the friction behavior between piston ring and cylinder liners pair by a reciprocating tester depending on the load, revolution and temperature. The results showed that lubricant type and revolution have been found significant on friction behavior.

Opis:: In this study, the effects of nucleus diameter on tensile-peel strength in electrical resistance spot welding were investigated. Taguchi design approach has been employed to the experimental planning, the $L_{27}(3^{13})$ orthogonal array. The larger-the-better and the nominal-the-best response criteria were selected to obtain the optimum conditions for nucleus diameter and tensile-peel strength, respectively. In addition, the effects of five parameters, electrode pressure, clamping time, welding current, welding time, and holding time, were examined in this way. Results showed that the tensile-peel strength was related with nucleus diameter, and that welding current and welding time were the most effective parameters for improvement of the strength of weld joints.

Opis:: In this study, mechanical and wear behaviour of polymer-boride composite ($AlB_2$/PE) materials produced through pressure moulding technique have been experimentally investigated. Three different composite materials that include 5 wt%, 10 wt%, and 20 wt% $AlB_2$ reinforcement phase were tested using pin-on-disk arrangement. Compared with the matrix, the 20 wt% $AlB_2$ composite shows a 71% increase in the ultimate tensile strength and the highest wear resistance.

Opis:: Aluminium-boride composites ($Al-AlB_2$) having two different volume fractions of reinforcing ($AlB_2$), namely 4.0 and 10.0 per cent have been produced through synthesizing boron by reaction of boron oxide ($B_2O_3$) with liquid aluminium. Friction and wear characteristic of the composites have been investigated under dry sliding condition and results compared with pure aluminium. The wear rate increases with normal load and sliding speed and is significantly lower with the composites when compared to that of monolithic material. The coefficient of friction increased with increasing volume fraction of $AlB_2$ reinforcement phase. The wear rate, however, decreased with increasing volume fraction of $AlB_2$.
