Introduction

Zude Zhao is a prominent inventor based in Chongqing, China. He has made significant contributions to the field of shaped charge liners, with a focus on enhancing their performance and stability. With a total of 4 patents to his name, Zhao's work is recognized for its innovative approaches and practical applications.

Latest Patents

Zhao's latest patents include a preparation method for a uniform low stress cone shaped charge liner. This method involves multi-pass extrusion forming, vibration aging treatment, and cryogenic treatment. The multi-pass extrusion forming consists of 4 to 8 passes of extrusion deformation, which occurs under a three-dimensional compressive stress and a deformation rate of 5 to 10 mm/s. Each pass has a deformation amount of 5 to 50%. The resulting shaped charge liner boasts high dimensional accuracy, good geometric symmetry, low stress value, and excellent stability during precise machining and use. This innovation significantly improves the penetration capability and stability of high-explosive anti-tank warheads.

Another notable patent is the gradient control method for microstructure ultrafine crystallization of a deep cone copper shaped charge liner. This method includes extrusion forming, recrystallization heat treatment, and high-frequency percussion. The extrusion forming utilizes multi-pass extrusion, while the high-frequency percussion step operates at a speed of 30,000 to 40,000 times per minute, with a percussion force ranging from 1600 N to 2000 N. This innovative control technology enhances the plasticity of the material and results in fine crystal structures, forming an ultrafine grain gradient structure along the thickness direction of the shaped charge liner.
