要使任何新方法或技术的优越性的主张令人信服，必须提供更好的性能、加工和经济性的有形证据。多年来，气体渗氮并不是一种流行的表面硬化工艺，因为渗氮层固有的脆性深深扎根在集体记忆中。通过引入可控气体渗氮技术，实现了渗氮技术的重大突破。可控气体渗氮是一种利用渗氮电位作为控制参数的工艺。该工艺可实现最佳功能，包括氮化零件的性能，消除脆性，以及工艺便利性和经济性。

To make claims about the superiority of any new method or technology convincing, one must provide tangible proof of better properties, processing and economy. For many years, gas nitriding was not a popular surface hardening process because ingrained in collective memory was the inherent brittleness of the nitrided layer. A significant breakthrough in nitriding technology was accomplished with the introduction of controlled gas nitriding - a process utilizing the nitriding potential as controlling parameter. This process can be implemented to bring out best features which include properties of the nitrided part, with elimination of brittleness, along with process facilitation and economy.
