Kermetico, Benicia, Calif., makes specialized HVAF systems to spray metal coatings and alloyed powder compositions onto uncommon substrates such as acme threads, thin walls, and temperature-sensitive materials.
Continue readingSpray Tips: Cold spray particle velocity and temperature
The diagram compares the particle velocity and gas temperature ranges of cold spray and other thermal spray processes: In the cold spray process, the gas and particle temperatures are much lower and the gas and particle velocity are much higher than in other thermal spray processes.
