Spray coating processing SPRAY PROCESSING
Detailed Explanation of Cold Spray Technology
Cold spray technology, an advanced surface treatment process, has attracted considerable attention in recent years. It involves atomizing metal powders or other materials at extremely low temperatures and precisely spraying them onto a substrate to form a dense coating. This technology is not only suitable for metallic materials but can also be used to coat non-metallic materials such as ceramics and plastics, demonstrating broad application potential.

A Detailed Explanation of Cold Spray Technology: Working Principle, Applications, and Market Challenges
1. Overview of Cold Spray Technology
Cold spray technology, an advanced surface treatment process, has attracted considerable attention in recent years. It involves atomizing metal powders or other materials at extremely low temperatures and precisely spraying them onto a substrate to form a dense coating. This technology is not only suitable for metallic materials but can also be used to coat non-metallic materials such as ceramics and plastics, demonstrating broad application potential.
1.1 ► Technical Principles and Features
Cold spray technology involves coating deposition at low temperatures, resulting in coatings with low residual stresses—primarily in a compressive stress state—and coating thicknesses that can reach several millimeters. This technology... Has a minimal thermal impact on the substrate. During the spraying process, the powder remains free from oxidation and contamination, and the coating’s properties largely retain those of the original material.
1.2 ► Equipment and Processes
The principle of cold spray equipment is to utilize compressed gas (typically... (N2 or He) transports the powder into the spray gun, where it is heated and accelerated through the expansion of a Laval nozzle, causing the powder to impact the substrate at supersonic speeds. Since the heating temperature is significantly lower than the material’s melting point, The powder is deposited at high speed in the solid state, forming a dense coating. 。
02 2. Material applicability and price
The application range of cold spray technology is limited; currently, it is restricted to metal and alloy powders that can undergo plastic deformation.
2.1 ► Applicable Materials
Commonly used metal coating materials include: Cu, Al, Ni, and others; commonly used alloy powders include NiCr, NiCrAl, CuAl, and so forth. However, Certain materials that are prone to strain hardening, such as: 317L stainless steel and TiAl8V4 are not suitable for cold spray technology. 。
2.2 ► Equipment Price
Price factors for cold spray equipment: Cold spray equipment consists of multiple components, including a control unit, spray gun, heater, powder feeder, spraying robotic arm, and dust extraction and filtration system. Since the current application scope of this technology is relatively narrow, The equipment has not yet been mass-produced, so its price is relatively high. Commercial cold-spray equipment on the market is mainly imported, with the price range for high-pressure cold-spray equipment falling within... Between 2 million and 5 million, while low-pressure cold spray equipment costs around 200,000.
03 3. Technological Advantages
Cold spray technology, as an advanced coating preparation method, boasts numerous advantages.
3.1 ► Advantages
Cold spray technology enables efficient material deposition at low temperatures. Not only does it avoid the potential risks associated with high-temperature coating processes, but it also boasts high deposition efficiency and excellent coating quality, making it an irreplaceable choice in certain specialized application fields.
04 4. Company Introduction
Guangzhou Sanxin Metal Technology Co., Ltd. Specializing in the process R&D and manufacturing of precision aerospace components, we are a high-tech enterprise integrating R&D, production, and sales.
