Title: Increasing tensile and vibrational strength of metal surface - by producing induced magnetic stress in surface area using current carrying rod
Inventor: EIFELER DIETMAR PROF DR
IPC: C21D1/10
Filed: 1991-10-17
Abstract: The tensile and vibrational strength of metal surfaces is improved by subjecting it to a contact-free magnetic impulse using an electric conductor system which conducts a current of a million amps. ADVANTAGE - Avoid mechanical contact which could lead to microcrack formation and premature failure. Can embodiment the area around a drilled hole can be treated by running a conductor rod through the hole and discharging a storage battery in such a way that the magnetic field around the rod induces a counter flowing current in the metal plate which leads to a magnetic force being produced between the rod and hole wall.
