低温金属纳米粒子被高速喷涂到金属基体上的过程称为动能喷涂(KEM)。此法是由加州圣芭芭拉市的Inovati学院开发的。在该法中，金属粒子如Al、Ti或Cu与He或N在粉末流态化设备中混和，然后将其高速喷涂到金属基体上。当粒子打到基体上时，它产生足够的变形使表面积增大了约4倍， Low-temperature metal nanoparticles are sprayed onto the metal substrate at high speed is called kinetic energy spray (KEM). This method was developed by Inovati College in Santa Barbara, California. In this method, metal particles such as Al, Ti or Cu are mixed with He or N in a powder fluidization apparatus and then sprayed onto the metal substrate at high speed. When the particles hitting the substrate, it produces enough deformation to increase the surface area about four times,
