根据作者的研究成果,在经典化学热处理理论基础上把固体物理学新成就中的缺陷理论与扩散理论及析出相固溶析出理论和晶粒细化超细化理论相融合,首次提出了以稀土、间隙碳、氮原子Cottrell气团为核心的稀土化学热处理创新理论,在该领域开创出一种全新的扩散模式。创建了钢中新的稀土渗碳、稀土渗氮及稀土氮碳共渗工艺体系。新体系不仅显著提高了扩散速度,同时又能显著改善微观组织和大幅度提高使用性能,使齿轮类零件的使用寿命显著提高。
According to the research results of the author, based on the classical theory of chemical heat treatment, the defect theory in new achievements of solid state physics is merged with the theory of diffusion, the theory of solid solution precipitation of precipitates and the theory of ultrafine grain refinement. , Interstitial carbon and nitrogen atom Cottrell gas cluster as the core of rare earth chemical heat treatment theory of innovation in the field to create a new diffusion mode. Create a new steel in the rare earth carburizing, rare earth nitriding and rare earth nitrocarburizing process system. The new system not only significantly increased the proliferation rate, but also significantly improve the microstructure and significantly improve the performance, so gear parts life significantly improved.
