Problems solved by technology

The existing soft body armor is light in weight, but there are still many problems in terms of protection, such as poor protection effect, etc.; the advantage of hardware body armor is that the protection effect is good, but the disadvantage is also obvious that it is heavy and inconvenient to carry

Abstract

The invention relate to a coating method for preventing high-speed impact. The coating method comprise the following steps that preliminary ion cleaning is carried out on the surface of a substrate; the substrate after surface cleaning is subjected to laser subsurface microstructure; after deep cleaning on a structured surface, ion implantation is carried out and annealing is carried out to form apseudo diffusion layer; a polymer energy-absorbing film layer is deposited on the pseudo diffusion layer by an evaporation method; a polymer layer is metallized by polymer layer by high energy ion implantation; a superhard diamond coating is deposited on a metallized layer by using magnetic filtration deposition equipment; and the polymer layer, the metallized layer and a superhard diamond-like carbon layer are circularly prepared for 3-5 times. According to the coating method provided by the invention, the impact resistance of the matrix against high-speed moving objects is obviously improved by combining a matrix microstructure, ion implantation and deposition coating. The coating method is simple and easy to operate, low in cost and high in efficiency, and thus is very suitable for batch production.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on May 22, 2019, with the application number CN201910430883.2 and the invention title "An Anti-High-Speed ​​Impact Coating Method", the entire contents of which are incorporated herein by reference In this application. technical field [0002] The invention relates to a preparation method and application of an anti-high-speed impact energy-absorbing coating, which belongs to the technical field of protective materials. Background technique [0003] Body armor is personal protective equipment worn to ensure human survival in a specific environment. It can absorb and dissipate the kinetic energy of bullets and fragments, prevent penetration, and effectively protect the protected parts of the human body. At present, body armor mainly refers to the bulletproof vest that protects the front chest and back, and prevents stray bullets and fragments from causing damage t...
