How Cold Spraying Works?
Cold spraying is an advanced coating process where metal powders are accelerated through a high-speed gas stream and bonded to a surface—without using heat. This preserves the base material’s integrity while creating dense, durable coatings ideal for cookware, aerospace, and more.

Understanding Cold Spray Technology
Cold spraying is a solid-state coating process where fine particles are accelerated at high speeds to form strong, dense layers—without melting the material. The quality of the coating depends on precise control of particle velocity, making it ideal for sensitive, high-performance applications.
Critical Speed – The Bonding Threshold
For a coating particle to bond effectively to the surface, it must strike at or above a specific minimum velocity called the critical speed. This value differs for each material and is essential for strong adhesion.
Above Critical Speed – Improved Adhesion
Once the particle exceeds its critical speed, deformation increases at impact—enhancing the mechanical interlock between the coating and the component for a tighter, more durable bond.
Erosion Speed – When Too Much is Harmful
If particles travel too fast and reach erosion speed, they may start to damage the surface, causing material loss instead of forming layers—compromising coating quality.
The Optimal Range – Strong and Stable Layers
The best coating results happen when particle velocities stay between critical and erosion speeds. This balance ensures dense, robust coatings with high performance and durability.
What Makes Cold Spray Technology Unique
Cold spraying is a cutting-edge surface coating process that uses high-velocity gas to apply material without melting it. This solid-state approach delivers superior coating quality, excellent material retention, and outstanding versatility—ideal for precision-critical industries like cookware, aerospace, and automotive.
No Heat Distortion
Cold spraying is a solid-state coating process, meaning the particles never melt. This eliminates the thermal stress, warping, or microstructural changes typically caused by high-temperature processes. As a result, sensitive components can be coated without risk of damage, preserving their mechanical and chemical integrity. It’s a perfect solution for applications where heat exposure is unacceptable, such as aerospace parts, cookware surfaces, or precision tools.
