The increasing interest in functionally graded materials for automobile, military, and aerospace structural applications in recent years is due to its admirable properties such as good resistance to thermal fluctuation, good formability, and good strength. This study investigates the tribological property of aluminum A356 composites reinforced with silicon carbide particles with varied weight-percents and particle sizes fabricated through centrifugal casting technique. Tribological, mechanical, and SEM analyses were carried out on fabricated composite samples, reinforced with SiC p of 7 µ and 15 µ particle sizes, respectively. The results indicated that the insertion of the reinforcement particles in the aluminum matrix improved the microstructural properties of the fabricated composites and enhanced their tribological properties. Furthermore, this study confirms that the size of the reinforcement particles influences the overall properties of aluminium metal matrix composites. Polishing was done using an automatic polishing machine with different microns of diamond suspensions and fumed silica on polishing cloths. The polishing process continued until a mirror-like surface was achieved. The samples' surfaces were further etched using Keller's reagent to reveal adequate details during the microstructural examination. The mechanical properties of hardness, tensile strength, and wear behavior of the FGM cast samples were also investigated. The individual sectioned samples were subjected to a hardness test to determine the effect of the different particle sizes with the varying concentrations of the reinforcement particles along each sample's length on their respective hardness properties. The hardness test was carried out using the LECO ® M-400-H1 hardness testing machine with a load of 100 g and a dwell time of 15 sec. The hardness value for each sample was determined by taking the average values obtained from five indentations on the sample's surface to be examined. The uniquely developed FGAMMC presented in this paper was subjected to tribological analysis using a pin-on-disc Anton Paar tribometer. A stainless steel counterface with a surface roughness of 15 nm, a load of 5 N, a sliding distance of 400 m, and a motor speed of 100 rev/min was used to determine the tribological property of the samples. The samples' worn surfaces were further examined using SEM to investigate the wear tracks formed and the interaction between the counterface material and samples' surface.

Nigeria is a theatre for many cybercriminal activities and attacks that have constantly threatened her national security. Many institutions, including financial and telecommunications, have continued to suffer huge monetary losses as a result of cyber war declared on the nation by certain criminal elements in the society. The vulnerability of cyberspace has allowed the invasion of Nigeria's cyber infrastructure and consequently impacting negatively on national security. The need to secure national cyberspace has become more urgent than ever because of the sharp increase in cyber threats that are capable of grounding national facilities and other critical economic systems. The capability of criminal state and non-state actors to infiltrate cyberspace and attack private and public businesses have further made it imperative for countries to reassess their cyber security and cyber warfare capability. Consequently, this paper interrogates Nigeria’s cyber warfare capability as a tool for enhancing national security.
