上千元一把的拉刀,经过离子镀渗处理后,寿命可提高1倍,铰刀、钻头则分别提高寿命5—7倍或7—8倍。由南京航空学院研制的这项表面处理技术,于最近通过了技术鉴定。在高速钢刀具表面采用离子镀涂层技术镀上一层金黄色的氮化钛后,可使刀具的硬度、抗粘结性、化学稳定性以及韧性等性能大大提高,从而有效地提高刀具耐用度和加 A thousand dollars a broach, after ion plating infiltration treatment, the life expectancy can be increased by 1 times, reamer, drill bit, respectively, to increase life expectancy 5-7 times or 7-8 times. The surface treatment technology developed by Nanjing Aeronautical Institute recently passed the technical appraisal. Plating a layer of golden yellow titanium nitride on the surface of HSS tool can greatly improve the tool’s hardness, anti-sticking property, chemical stability and toughness, thus effectively increasing the tool’s durability Degree and plus
