中文摘要：
利用高能喷丸技术实现电工纯铁表面自纳米化,通过X射线衍射分析对表面变形层晶粒度进行表征;然后在Gleeble 1500型热模拟试验机上进行Ni的扩渗;利用扫描电子显微镜作能谱分析,对常规粗晶和纳米晶试样的扩散效果进行分析。结果表明,电工纯铁经喷丸处理,表面得到了纳米结构层;Ni在纳米晶中的扩散系数比同等条件下常规粗晶试样高1倍。
英文摘要：
High-energy shot peening technology was used to make pure iron surface self nano-crystallization （SSNC）, The grain size was characterized by X-ray diffraction analysis （XRD）. And then Ni was diffused to iron on the Gleeble 1500 thermal simulation testing machine, the SEM was used for spectrum analysis to com- pare the proliferation effect of samples before and after SSNC. The results showed that the surface of pure iron was nano-structured after the shot peening treatment. Diffusivity of Ni under the same conditions on the surface of specimen was bigger at the shot peening side than the side without shot peening.
