Title: **The Innovative Contributions of Dong Gil Ahn**

Introduction

Dong Gil Ahn, based in Daegu, South Korea, is a distinguished inventor with a total of three patents to his name. His work focuses primarily on cutting tools and their surface treatments. Ahn's innovations are notable for their impact on tool performance and longevity, showcasing his dedication to advancing textile technology.

Latest Patents

Among Ahn's latest patents is a surface treating method for cutting tools. This invention involves a procedure where if the outermost ceramic coating layer is a β-Al2O3 coating layer, a certain micron thickness of this layer will undergo transformation into an α-Al2O3 through instantaneous melting, vaporization, and solidification. The patented method enhances surface roughness, particularly when the outermost layer consists of an α-Al2O3 coating layer. The melting of the surface not only improves the texture but ensures it solidifies smoothly due to the surface tension during the melting phase.

Another significant patent from Ahn involves a method for pre-treating a coating that significantly enhances both the surface roughness and the bonding force of the coating layer on cemented carbide cutting tools. This method effectively removes a sintered surface layer within 0.5-5 μm from the substrate of a cemented carbide cutting tool, transitioning the surface from a porous, non-uniform structure to one with high density and evenness. To achieve a strong bond between the coating layer and the substrate, the surface area of open pores remaining after removal must be at least 5%.
