利用中国独创的双层辉光离子渗金属技术，在普通低碳钢及低合金钢表面渗入所需合金元素，再经渗碳，形成具有高速钢成分的渗层，即在钢的表面形成高速钢，称为双层辉光离子渗高速钢（简称双辉渗高速钢）。由于这是一种固态冶金法，没有由于结晶而形成的粗大一次碳化物，合金层中的碳化物细小且分布均匀，避免了传统的冶炼、锻轧高速钢生产中难以克服的碳化物不均匀问题。合金元素供给源采用粉末冶金法制成，可根据实际需要调整其组分配比，从而获得一系列具有不同成分的高速钢渗层
The use of China’s original double glow ion infiltration metal technology, ordinary low carbon steel and low alloy steel surface infiltration of the required alloying elements, and then by carburizing, forming a high-speed steel composition of the infiltration layer, that is, the formation of high-speed steel surface Steel, called double glow ion permeation high speed steel (referred to as double hurst infiltration high speed steel). Since this is a solid state metallurgical method, there is no coarse primary carbides formed by crystallization and the carbides in the alloy layer are small and evenly distributed, thus avoiding the inconvenient carbides unevenly produced in the conventional smelting and forging high-speed steel production problem. Alloying elements made by powder metallurgy, can be adjusted according to actual needs of its component ratio, so as to obtain a series of different composition of high-speed steel layer
