Latest Patents

Haiji Chen holds a patent for a micro-nano incremental mechanical surface treatment method. This method involves several steps, including the use of a modification tool with a designable end that contacts the surface of a substrate material. The tool is rotated in a local region while compressing the material surface. Processing parameters are preset using 3D modeling software. After processing the entire surface, the tool moves downwards to the previously indented surface. This process continues until the surface material reaches a pre-defined thickness, achieving grain refinement and improved surface performance. The method is particularly advantageous for workpieces with complex shapes, offering high bonding strength, low pollution, and cost-effectiveness.
