Laser Powder Bed Fusion of Invar-based Metal Matrix Composites Reinforced with Ceramic Particles: Relationships Between Residual Stresses, Microstructure, and Mechanical Properties
Date: Feb 2022 - Dec 2025
Stellenbosch University, South Africa
This research advanced the properties of Invar, an Iron-Nickel alloy, by creating three novel Invar metal matrix composites using titanium carbide, titanium nitride and titanium-carbonitride particles. Laser powder bed fusion manufacturing process parameters were determined according to a design of experiments and statistical approach. The new materials achieved 62-86% higher hardness, 38-73% greater tensile strength, and 23-60% improved wear resistance compared to Invar. Relationships between microstructure, processing parameters and residual stresses were established, with a manufacturing feasibility framework developed. This new manufacturing approach has the potential to increase the service life of Invar components without compromising established thermal properties.

Development and Performance Evaluation of a Prototype Oil Palm Fruit Harvester
Date: Jan 2018 - Apr 2021
Ahmadu Bello University, Nigeria
Palm oil is the world’s most productive edible oil crop, yet in Nigeria, it is still mostly harvested traditionally by climbing. As the country’s population grows, demand for palm oil has surpassed local production. Traditional harvesting methods become unsafe and difficult once trees grow taller than 3.5 m, while mechanical tools like Cantas and Ckat are too costly for small-scale farmers. This study developed and tested an electromechanical oil palm harvester in Oyo State, Nigeria, with an Arduino communication system linked to an Android app for control and feedback. The results demonstrated reliable performance, characterised by accurate motor responses and satisfactory climbing and descending speeds.

Design and Fabrication of a Light-Weight and Effective Braking System for a Shell Eco-Marathon Vehicle
Date: Aug 2010 - Nov 2015
Ahmadu Bello University, Nigeria
A lightweight and effective braking system was developed for the Shell Eco-marathon vehicle using locally available materials. It met the design goals and passed technical inspection. The system produced a braking force of 4022.1 N, stopped within 5.93 m, and could hold the car on a 12.95° slope. For future improvements, computer simulations should be used to study stress points, and proper measuring tools should be included for testing. Additionally, lighter materials such as aluminium or carbon fibre were recommended to enhance safety and reduce overall weight.
