Title: Innovations of Changyu Wang in Laser Shock Peening Technology

Introduction

Changyu Wang is a notable inventor based in Jiangsu, China, recognized for his contributions to the field of laser shock peening technology. He holds two patents that focus on enhancing the performance and durability of materials, particularly in the context of permanent magnetic materials and turbine blades.

Latest Patents

One of his latest patents is titled "Laser shock peening method for improving the corrosion resistance of sintered Nd-Fe-B magnet." This patent discloses a surface modification technique for permanent magnetic materials. The process involves immersing a sintered Nd-Fe-B magnet in a chlorine-containing solution to corrode its surface after it has been ground, polished, and cleaned. This treatment creates atomic vacancies or gaps at the grain boundaries in the surface layer of the magnet. Subsequently, compound nanopowders coated on the surface are implanted into the grain boundaries through laser shock peening, resulting in a gradient nanostructure layer. This method significantly enhances the corrosion resistance of the sintered Nd-Fe-B magnet.

Another significant patent by Wang is the "Double-side synchronous laser shock peening method for leading edge of turbine blade." This innovative method employs two laser beams with the same diameter but different pulse energies to synchronously shock both the front and back sides of the leading edge of turbine blades. The greater laser pulse energy on the front side generates dynamic plastic deformation, while the back side's energy balances excessive shock-wave pressure, preventing macroscopic deformation. This technique ultimately achieves an optimal strengthening effect for turbine blades.
