Bringing Productivity and Innovation Benefits to Many Markets

The compelling productivity and quality benefits of cold spraying are driving demand for this process across a broad spectrum of industries from automotive through electronics to aviation. Unlike hot spraying, which heats the powder to above melting point, cold spraying requires a powder temperature of "just" a few hundred degrees Celsius. With cold spraying, tiny particles of metal powder are propelled onto a substrate using high-pressure gases such as nitrogen or helium. The particles are heated and accelerated through a supersonic nozzle to speeds of between 500 and 1200 meters/second. The supersonic speed of the particles and the high degree of deformation on impact with the substrate enable extremely homogenous and very dense coatings. Because this process does not fuse or melt the powder, it results in minimal thermal influence on the coating and the substrate.

The gas supply system plays a defining role in cold spraying outcomes. A stable, reliable stream of high-pressure, high-purity process gases is essential. Gas pressure and temperature determine the particle velocity and - by definition - the quality of the coating. These parameters must also be adapted to each cold spray application. Any fluctuations in temperature or pressure compromise coating quality; with rapid temperature changes even potentially damaging both the gas heater and the spray nozzle.
