In most induction heat treating applications, the expected lifetime of the inductor is limited by the fatigue life of the copper.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">In some of the most severe cases, the lifetime of the inductor is limited by the lifetime of the magnetic flux controller. In these applications, corrosion is a typical failure mode of the magnetic flux controller. Corrosion of the soft magnetic particles in the composite is caused by a combination of elevated temperatures and exposure to oxidizing agents (quenchants, air, etc.). Coating SMCs can significantly enhance their corrosion resistance, improving their durability.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">In this study, four commercially available SMCs, Ferrotron 559H, Fluxtrol 100, Fluxtrol 50, and Fluxtrol A, were coated with three different types of high performance ceramic polymer-based coating materials. ASTM D1735 humidity tests were carried out for 48, 96, and 168 hours on all the samples. The researchers presented results of the corrosion testing, including a comparative analysis of three types of coatings. They also discussed the potential impact on inductor lifetime. <\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p><b>Title: <\/b><strong>Improving Corrosion Resistance of Soft Magnetic Composites for Induction Heat Treating Applications<\/strong><\/p>\n<p><b>Authors: <\/b><b><i><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\"line-height:107%\"><span style=\",sans-serif\"><span style=\"color:#333333\">Dr. Prem Vaishnava, <\/span><\/span><\/span><\/span><\/i><\/b><i><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\"line-height:107%\"><span style=\",sans-serif\"><span style=\"color:#333333\">R.
