It is the nitrided surface itself that is largely responsible for increased interest. The surface engineering that is possible along with its predictable and relatively distortion-free results are huge factors in its growth.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Two nitriding technologies have become dominant in recent years: gas and ion. Gas nitriding has grown from simple atmosphere furnaces using single or two-stage processes, to advanced vacuum-purged equipment that can accurately predict and control nitriding potential. <\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Ion (plasma) nitriding has progressed from plasma heating in cold wall vacuum furnaces, to the use of hot wall technologies and pulsed plasma. Both processes and their advances were discussed, as each offers engineers choices that result in properly nitrided parts capable of meeting the most stringent requirements.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><b>Title: Nitriding \u2013 Its Growth and Tribological Benefits for Surface Engineering<\/b><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"background:white\"><span style=\"line-height:normal\"><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\",sans-serif\"><span style=\"color:#333333\">Authors<i>: Mark Hemsath, <\/i><\/span><\/span><\/span><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\",sans-serif\"><span style=\"color:#333333\">Seco Vacuum Technologies LLC, Meadville, Pennsylvania<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"background:white\"><span style=\"line-height:normal\"><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\",sans-serif\"><span style=\"color:#333333\"><a href=\"http:\/\/www.secovacusa.com\">www.secovacusa.com<\/a> <\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"background:white\"><span style=\"line-height:normal\"><i><span style=\"border:none windowtext 1.0pt;font-size:10.5pt;padding:0in\"><span style=\",sans-serif\"><span style=\"color:#333333\">Prof. Daniel H.
