这是人家公司的核心专利，知道个名就不错了，还想知道细节。
你想花钱它也不会给你的，山寨还山寨不了。

以Kolsterising与Nivox技术为主打的特种不锈钢处理（S3P）为奥氏体不锈钢、镍基与钴铬铸造合金提供了一个独一无二的表面硬化解决方案，在不影响材料的抗腐蚀性能的条件提高了其机械性能与耐磨性能。
经过最近二十多年的发展，欧洲、美国和日本在奥氏体不锈钢耐蚀表面硬化技术方面走在前列，部分工艺已形成工业化应用。

Kolstering工艺影响最大，已在欧洲和北美形成规模化工业应用。该工艺20年前由荷兰人Kolster发明并创立公司，率先在欧洲实现工业应用，后被国际热处理行业知名企业Bodycoat收购，2003年该工艺被介绍到北美。Kolsterising工艺的核心内容是较低温度下，通过一定时间的气体渗碳处理来获得碳扩散强化层。主要特色是通过特殊的预处理方法去除奥氏体不锈钢表面的钝化层，并保证在整个渗碳处理过程中，其表面不生成新的钝化层。这种特殊的预处理方法目前还处于保密状态。奥氏体不锈钢经Kolsterising处理后表面显微硬度可达1000～l200HV0.05，常规耐蚀性能没有下降，耐孔蚀性和耐应力腐蚀开裂性能明显改善。
Nivox® processes represent a group of Bodycote patented plasma based diffusion treatments such as nitriding or nitrocarburising for various steel grades, in particular stainless steel, as well as nickel base and titanium alloys. The treatment significantly improves surface hardness and resistance against abrasive wear. The gentle process prevents distortion and dimensional changes. Depending on the process, pure nitriding – with or without compound layer – or nitrocarburising to improve the component properties can be applied.

The special process technique of Nivox® also allows for the surface hardening of corrosion resistant materials by nitriding or nitrocarburising, creating the so called S-Phase that can be mainly found in the nuclear power industry, as well as in mechanical engineering and aeronautics. The corrosion resistance of the treated components is mainly unaffected and guarantees optimal mechanical, wear and corrosion properties.
