Introduction

Cold spray additive manufacturing is a type of metal additive manufacturing process that has been applied in aviation, aerospace, automobiles, molds and other fields.

During the entire additive manufacturing process, both the base material and the deposited material remain in a solid state and can be processed without or with minimal metallurgical changes.

Under the premise of the deposited material on the surface of the base material, the additive manufacturing of the deposited material is realized. Because it does not need to put the base material into a specific forming chamber, it can It is possible to realize additive manufacturing on the surface of the component without being limited by the size of the powder bed.

Cold spray additive manufacturing is a solid-state deposition process that has the advantages of high deposition efficiency, low porosity, good bonding strength, and no The fire has little effect on the properties of the substrate and the deposited material. The deposited body has small residual stress and usually has compressive stress. The powder does not It is prone to oxidation, decomposition, phase change and grain growth of nanostructured materials, and is particularly suitable for oxidation-sensitive, temperature-sensitive and phase-change-sensitive materials.

It is widely used in high-quality coating preparation of materials such as 3D conformal additive manufacturing of complex curved surfaces and connection of insoluble heterogeneous metals.

The metal powder materials used include aluminum alloy, copper alloy, titanium alloy, stainless steel, etc.

This document describes the general requirements, process, product inspection and technical documentation delivery of the cold spray additive manufacturing process.

Provide process control methods, process evaluation and quality inspection basis for related enterprises in the cold spray additive manufacturing process, and improve the quality of cold spray additive manufacturing.

It can improve the quality stability and reliability of products, promote the development of additive manufacturing industry in a more orderly, reasonable and economical direction, and have good economic benefits. and social benefits.
