Magnetic Materials Brittle Particle Cold Spray
TTEC’s unique and patented process requires no binder. During the Brittle Particle Cold Spray process the magnetic material particles adhere to themselves and to the surface forming a nearly 100% dense, pure magnetic material deposit.
Neodymium Iron Boride and Ferrite Magnetic Materials have been demonstrated.
Additional hard and soft magnetic Material formulations currently under test.
