Abstract: Documentation on the correct process parameters and component requirements for setting up efficient aluminum powder production systems capable of manufacturing powder that meets the requirements for the selective laser melting (SLM) process is not available due to its proprietary nature. This hinders powder metallurgy (PM) trainees in acquiring knowledge and skills needed in setting up such metal powder production systems. To address this challenge, powder requirements for the SLM ...

In this thesis the Variable Frequency Derive control the speed of 3-phase induction motor based on programmable logic controller and supervisory control and data acquisition technology. An implementation of a hardware and software for speed control, direction control, parameter monitoring on supervisory control and data acquisition screen is also provided. tank filling ,bottle filling and capping system ...
ABSTRACT The project is on the tDevelopment of Automobile Br&e Linings using materials and methods. Five dis= brake linings of the geometrical specification of Peugeot 504 series were produced using the available equipment at the Mechanical Engineering Department of the University of Nigeria, Nsuklira, The friction pads were made of varying proportions of palm kernel shell as the base friction material, rubber latex, rubber dust, sulphur, clay, brass chips and Epoxy Resins. Laboratory tests...
ABSTRACT Body amour describes the object that is worn or carried to provide an individual protection against external energy. This research work was carried out to formulate powdered alumina for body amour application. Alumina powder (Al203), magnesium oxide (MgO), calcium oxide (CaO) and polyvinyl alcohol (PY A) were the materials used in the formulation procedure for the research work, the materials were mixed thoroughly to form six different formulation samples; binder and alumina po...
ABSTRACT Steam boiler is a closed vessel which is used to produce steam from water by combustion of fuel. Steam is important in engineering and energy studies. It is use to sterilize laboratory equipment, for heating applications and also used to generate power. A laboratory fire-tube boiler was design and constructed from a conceptual physical geometry, making necessary design calculations from which dimensions and other deductions were made, and finally developing a working drawing. A b...
ABSTRACT The PEDAL POWERED WASHING MACHINE is a project, which is undertaken to solve the problem of electric supply to people in rural areas. To run a washing machine, the source of power is electricity. In Nigeria most of the villages are suffering from shortage of electricity. So to overcome above problem we select the washing machine, which is operated manually. It requires no electric power supply or diesel supply. This project is low weight & portable can be easily transported. We�...
ABSTRACT The decrease in availability of fuel wood and rise in prices of fo~sil foels in Nigeria calls for considering alternative sources of energy for domestic and industrial use. This project was carried out in order to design and develop a low cost briquetting machine for rural communities. It involves the modificaion of hand use in producing briquettes by employing the use of hydraulic jack, moulds, pistons etc. This method is faster and easier. The agricultural residue used was 80% saw...
ABSTRACT Failure of engineering components in service, especially in marine applications, has recently been a major global concern, and corrosion resulting from biofouling has been the primary source of these failures. Ultimately, biofouling and corrosion are detrimental to the lifespan of parts in service. Thus, there is a need to develop protective coatings which are highly resistant to the biofouling-corrosion system. This study developed affordable, eco-friendly and durable bi-phase of Zn...
ABSTRACT African nations have been characterized by conflicts, total war, slave trade, poverty of the highest order, corrupt leadership, undeveloped infrastructures, indisciplined society, we can go on to mention as many as the vices that estranged the continent. It is an irony to see all these in African continent, where civilization of the world began. For all these calamities that befell Africa, I sometimes wonder, if that is why the observation of our God in Genesis 6:5 was made. “The L...

ABSTRCT Materials have been the milestones of progress. All civilizations have been categorized by the materials they used; The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God crea...
Abstract The Use Of Ferrous Gluconate As Corrosion Inhibitor On Aluminium Alloy In 0.5M H2SO4 Solution Was Studied Using Gravimetric And Potentiodynamic Polarization Measurements. The Surface Morphology Of The Aluminium Alloy Was Studied After Exposure To 0.5 M H2SO4 Solution In The Presence And Absence Of Inhibitor Using High Resolution Scanning Electron Microscopy Equipped With Energy Dispersive Spectroscopy (HRSEM – EDS). The Adsorption Behaviour Of The Inhibitor Was Investigated. T...
ABSTRACT The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God created the heaven and the earth”. So the earth was either created simultaneously with the heaven or it was c...
Abstract This research forms part of an ongoing HCCI study at the SASOL Advanced Fuels Laboratory to investigate and understand engine configuration and fuel chemistry effects on combustion in HCCI engines. This project continues from a previous project where a small Progress Aero Works (PAW) 6.5cc high speed model diesel" aeroplane engine was found to operate in HCCI mode with surprising ease and exibility. A 25cc, four-stroke, single cylinder Honda GX25 engine, possessing 2-valves with an o...
