Radical Nitriding Technolog<\/p>\n<\/div><\/div>

<\/div>

Radical nitriding is an advanced plasma nitriding method co-developed by Sumitomo Metal Mining Co., Ltd. and Japan Electronic Industry Co., Ltd.
\nIt combines a new theoretical understanding of plasma reactions with decades of heat treatment expertise to achieve highly controlled and stable nitriding results.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Principle and Overview of Radical Nitriding Equipment<\/p>\n<\/div><\/div>

<\/div>

Conventional plasma nitriding generates a high-energy plasma through DC glow discharge using a nitrogen-hydrogen gas mixture.
\nThis process heats the workpiece and activates its surface via energetic ion bombardment, while simultaneously forming nitrogen-based radicals that enable nitriding reactions.<\/p>\n

In contrast, radical nitriding applies a low-energy plasma generated by carefully controlled glow discharge using an ammonia-hydrogen gas mixture.
\nRather than relying on ion bombardment for heating, the workpiece is externally heated, while the highly active radicals formed in the low-density plasma drive the nitriding process.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
