With the aim of contributing to overcoming environmental regulations faced by industries, we are conducting tribology research to improve mechanical efficiency and durability, focusing on the following areas:

1. Tribochemical investigation for friction reduction
Under lubricated conditions, controlling tribochemical reactions at the sliding interface is a critical challenge for achieving friction reduction. This research aims to develop surface engineering strategies that optimize tribochemical reaction products that lead to low friction. Specifically, we seek to elucidate the decomposition mechanism of friction modifiers (e.g., MoDTC) during the friction process and fabricate surface coatings that enhance the formation of reaction products that contribute to friction reduction.

2. Superlow friction behavior of DLC under atmospheric and dry conditions
DLC coatings are known to exhibit superlow friction (friction coefficient < 0.01) in vacuum or inert gas environments. However, for industrial applications, achieving superlow friction in atmospheric conditions is essential. This research focuses on developing DLC coatings that maintain superlow frictional performance even in the absence of lubricants, enabling their application in real-world operating environments.
