求助各位大佬 有人听过Arcor V 处理吗?谢谢!
本帖最后由 gkbxybz 于 2018-3-5 13:01 编辑各位师傅 最近在设计的时候接触到Arcor V 表面处理, 对于这个处理 完全是无从下手,完全没有听过.不知道有哪位师傅听过有这方面资料的 谢谢. 这个是法国HEF公司的工艺，就是QPQ工艺。 HEF的工艺名称，和QPQ类似，只是盐不一样 舍舍夫（SURSULF)盐浴硫氮化技术和阿可（ARCOR)表面防腐处理技术,能极大提高表面硬度、耐磨性、耐腐蚀性、抗咬合性及抗疲劳强度，比其它表面处理如气体--氮化、离子氮化、镀铬处理等具有更优越的综合性能。从处理质量、环保以及价格等角度看，该工艺亦可替代如镀镍、铬、镉、锌等传统镀层工艺。-----网络资料
既然这个技术这么好为什么没有得到广泛应用呢？是由于价格？技术？还是其他？
ARCOR N is distinctive in that it is an austenitic, rather than a ferritic salt bath nitriding process. ARCOR N processing begins with immersion in an ionic liquid media, to produce a 10-25 micron surface layer of epsilon iron nitride above a nitrogen diffusion layer; an oxidizing bath to enhance corrosion performance; a rinsing step; and finally polymer impregnation, which seals the superficial voids in the iron oxy-nitride, further enhancing corrosion protection.
ARCOR N salt bath nitriding delivers both hardness and ductility during its short process cycle. Its ductile compound layer provides outstanding resistance to wear and corrosion. When used with its Corolac post-treatment bath, ARCOR N corrosion performance is up to 1000 hours, per ASTM B117.
Parts treated with ARCOR N salt bath nitriding effectively resist seizure. The micro-layer inhibits the formation of frictional welding points and assists the running-in of components. The hard, yet ductile surface layers make ARCOR treated parts compatible with mating surfaces without surface cracking or exfoliation. Finally, the ARCOR N process produces substantial improvements in fatigue resistance. ARCOR N has proved its ability to improve compound layer quality — particularly for cast irons — shorten cycle times, and reduce total costs.
ARCOR V was engineered specifically for automotive engine valves, but works well on all high chromium materials. This process provides two valuable benefits: a shorter process cycle, and highly uniform, repeatable results often difficult to achieve on high chromium steels. ARCOR V is also the best choice for nitrocarburizing of cast iron materials, due to the improved quality of the compound layer.
_______from http://www.hefusa.net/salt-bath-nitriding-arcor.html ARCOR V 的核心技术是盐浴铁素体氮碳共渗，它是专门设计用于汽车发动机阀门，也适用于所有高铬材料。这个工艺提供了两个有价值的好处：更短的工艺周期，以及高铬钢通常难以达到的高度均匀，可重复的结果。由于复合层质量的提高，ARCOR V也是铸铁材料氮碳共渗的最佳选择。
ARCOR N 的核心技术是盐浴奥氏体氮碳共渗。
