提高离子氮化的窄缝处理能力

Improving the effect of Ion Nitriding Process on Narrow-Slit Die

通过在工作气氛中加入氩气（Ar），可以提高离子氮化的窄缝处理能力；将这一结果应用于铝型材挤压模的强化处理工艺中，获得了很好的效果。

Adding Ar into furnace atmosphere,the effect of ion nitriding process on narrow-slit die can be improved. Applying this result into the treatment which strengthes dies used for extrusing aluminum shapes. We acquireexcellent economic benefit.
