The Amrita School of Engineering is pleased to announce a new research project led by Dr. Shubrajit Bhaumik, Associate Professor at the institution. The project, titled “Study of Wear in Timing Chains – Influence of Surface Treatments and Surface Finish,” aims to explore and analyze the wear characteristics of timing chains, specifically focusing on how different surface treatments and finishes can influence their performance and longevity. This research is particularly important for the automotive industry, specifically in the internal combustion engines of cars, trucks, and other vehicles where timing chains are critical for synchronizing the crankshaft and camshaft to ensure proper valve timing and engine operation.

Research Objectives and Significance

Timing chains play a crucial role in ensuring the proper functioning of engines, especially in regulating the timing of the engine’s intake and exhaust valves. Over time, these chains can experience wear due to constant friction and environmental factors. This wear can lead to a decrease in performance and even mechanical failure if not properly addressed. Therefore, understanding the tribological (friction, wear, and lubrication) behavior of these chains under different conditions is essential to improve their reliability.

The main objective of Dr. Bhaumik’s research is to conduct a thorough study on the tribological behavior of silent chain elements, a critical component of timing chains. The project will examine the influence of various surface treatments and surface finishes, which are believed to impact wear resistance and the overall performance of these chains. By understanding the effects of these factors, the team aims to develop better strategies for enhancing the life cycle of timing chains used in various mechanical systems.

Research Methodology

This study will involve testing timing chains under various environmental conditions, simulating real-world wear scenarios. Through rigorous experimentation and analysis, the project will provide valuable insights into the relationship between surface treatments, surface finish, and the wear characteristics of timing chains. The research will also explore how these treatments can be optimized for different operating conditions, such as temperature variations, load stress, and lubrication.

Funding and Support

This research project is generously funded by the TI India Murugappa Group. The funding is set for a period of 10 months, from October 2023 to July 2024.

Expected Outcomes

One of the key expected outcomes of this project is the submission of a comprehensive report detailing the findings of the tribological analysis. This report has already been compiled and submitted to the TI Chains Division, which will benefit from the valuable data and insights generated by this research. The results are expected to have significant implications for improving the design, manufacturing, and maintenance of timing chains, leading to enhanced performance and reduced wear.
The insights gathered from this study could also influence future innovations in materials science, particularly in the development of surface treatments and coatings that can increase the lifespan of vital engine components. By addressing wear issues at the microscopic level, the research may pave the way for more sustainable and efficient mechanical systems.
This project is a testament to the Amrita University’s School of Engineering’s commitment to advancing research in engineering and technology, with a focus on real-world applications that address critical challenges in the mechanical and automotive industries.
