Using Magnetized Water to Harden the CK45


CK45 steel has been hardened using magnetized water as a hardening media. The water has been exposed to a magnetic field of 1000 Gauss and 2000 Gauss respectively for periods of 1 to 5 hours, with flow rate 4 gal/min. The method ordinary hardening has been used in this research. It was found that the hardness increased directly with increasing the magnetic field and the exposure time and it reaches its maximum value at magnetic field intensity of 2000G and exposure time of 5 h. as maximum limits in this research.
