Prototyping a low-cost tribometer with block on ring configuration for the optimization of metal-forming applications

Applications in the metal-mechanic industry require the analysis and support of tribo-evaluations in their manufacturing processes. Experimentation with various metals and components could be performed under controlled conditions, including the ability to apply testing with a fluid or lubricant media or in dry conditions.
The aim of this work is to design and fabricate a working block for a ring tribometer at low cost. Present and future stakeholders will have the ability to analyze material properties in friction, wear, and displacement while saving the university over 500% in costs of an industrial tribometer. The integrity of the machine must adhere to ASTM G-77 guidelines and be able to withstand a load force up to 7.8 kg. Operation must be able to perform under the specified load function while maintaining 72 rpm. The machine will be housed in the Engineering Technology lab for easy accessibility and will also be on a cart for mobility options to different locations.
Consistent contact between surfaces causes friction and wear resulting in the loss of structural integrity of the material over time. Therefore, lubrication and design play an intricate role in improving the life of metals operating under various load conditions. The prototype tribometer was built at low cost, user-friendly and interactive to run research experiments on friction and wear under various conditions (metals, lubricity, etc.).
Alternative lubrication additives have become some of the industry's top sources to crack the code for longer lasting and more durable metal-forming applications. In this study, specimens taken from steel and aluminum-based metal samples were tested in a block-on-ring prototype for wear performance over various parameters including number of revolutions and time. Specimens also underwent tests with lubrication additives to further validate the life extent of metals under certain forces.
Experiments were conducted with block-on-ring prototypes on aluminum rings and steel specimens. The tribometer prototype was validated and satisfied the necessary operating protocols under ASTM standards (ASTM D2714, ASTM G77). This project was successfully completed by students from the Engineering Technology program at the University of XXX XXX.
