Impact EvoCSII Cold Spray System

General Introduction

The Impact EvoCSII cold-spray system is an integrated solution for industrial‑grade surface coating and additive manufacturing. Featuring a plug-and‑play, standardized configuration and highly modular scalability, it meets the diverse needs of both one‑off custom applications and large‑scale production runs. As an upgraded platform in the industrial cold‑spray sector, the EvoCSII boasts a comprehensively enhanced sensor suite, incorporating multi‑dimensional monitoring sensors that enable real‑time data acquisition and process‑state tracking throughout the entire cold‑spray workflow, significantly improving process control. Its core components have all been reengineered and optimized: from the spray gun and powder feeder to the gas‑management unit, each has undergone technological refinement, effectively enhancing coating deposition uniformity and density while supporting the spraying of a wide range of materials, including copper, aluminum, titanium, stainless steel, and various metal‑ceramic composites. Today, the system serves more than 12 major industries, including aerospace, automotive, and power generation.

Working principle

The Impact EvoCSII cold-spray system leverages the principles of high-pressure cold-spraying technology to enable both coating deposition and additive manufacturing. At its core, it uses a supersonic gas stream to propel powder particles, achieving solid-state deposition while completely avoiding high-temperature melting of the powder material—making it a cold‑state material deposition process. The system’s workflow is divided into three key stages: gas preconditioning, powder acceleration, and solid‑state impact deposition. First, an electronic control and gas‑management unit pressurizes the process gas (nitrogen, helium, or a mixture of both) to a specified pressure, up to 100 bar, before routing it to a preheating unit. Depending on the material being sprayed, the gas is heated to a predefined temperature range. The resulting high‑pressure, heated gas then enters a Laval nozzle, where its convergent–divergent geometry enables expansion and acceleration, generating a supersonic flow capable of propelling powder particles at speeds of up to 1,200 m/s.

Meanwhile, the powder feeder delivers metal or composite powders with an appropriate particle size into the gas stream at a precisely controlled rate. Within the supersonic gas flow, the powder particles are accelerated and uniformly mixed, and the solid particles—remaining unmelted—impact the substrate surface at high velocity. Under this high‑velocity impact, the particles undergo severe plastic deformation, forming mechanical interlocking and metallurgical bonding with the substrate surface. Simultaneously, the particles press against one another and fuse, building up layer by layer to create a dense coating or additively manufactured component. The EvoCSII system is equipped with multiple sensors that continuously monitor critical process parameters such as gas pressure, temperature, powder feed rate, and particle velocity, transmitting this data to the control system to enable real-time adjustment of the deposition process. To accommodate different spray gun models, the system allows for precise switching between pressure and temperature settings; for example, when paired with Type 6 or Type 11 spray guns, it can toggle between 50 bar/1100°C and 60 bar/1000°C modes, ensuring optimal process parameters for various materials and guaranteeing consistent deposition quality from the outset.

Advantages and Key Features

The core advantages of the Impact EvoCSII cold-spray system lie in its process reliability, production adaptability, and scalability, making it an industrial‑grade platform that balances manufacturing efficiency with process quality—its features align closely with real‑world industrial application requirements. In terms of productivity, the system supports up to four powder feeders operating in parallel, enabling high‑volume powder delivery, while simultaneously accommodating two spray guns for synchronized operation. This capability facilitates simultaneous dual‑side coating of workpieces, significantly boosting throughput per unit time and fully meeting the demands of large‑scale series production, thereby addressing the limitations of conventional cold‑spray equipment—namely, low efficiency and difficulty in scaling for batch applications.

In terms of process quality control, the system’s high‑density sensor array enables comprehensive parameter monitoring and data logging throughout the entire cold‑spraying process. All process data are captured, stored, and traceable in real time, providing precise data support for coating‑quality inspection, analysis, and optimization. This enhances process stability and consistency, effectively reducing product‑quality deviations caused by parameter fluctuations. The equipment features a modular system architecture, with each core component operating independently yet working in concert. This design allows for hardware expansion and upgrades tailored to production needs without requiring a full‑system replacement, while also simplifying maintenance: individual components can be inspected and replaced separately, thereby increasing equipment uptime.

In addition, the EvoCSII system boasts excellent compatibility, seamlessly integrating with all existing cold-spray accessories from the brand—eliminating the need to reconfigure auxiliary components for new equipment and thereby reducing users’ upgrade costs. The system features a completely new software architecture, with a streamlined and optimized user interface that aligns more closely with the practical demands of industrial production, lowering both the learning curve for operators and the incidence of operational errors. At the same time, the system incorporates standardized interfaces in advance to support future technological developments, leaving ample room for subsequent process upgrades and functional expansions, thus ensuring a robust technology lifecycle. In terms of material compatibility, the system can handle temperature‑sensitive materials such as copper, aluminum, and silver, while also accommodating high‑strength metals like titanium alloys and stainless steel, as well as metal‑ceramic composites. Its broad particle‑size range meets the diverse material‑spraying requirements across multiple industries.
