| 中文摘要: |
| 为提高奥氏体不锈钢lCr18Ni9Ti的硬度，对其表面进行激光表面强化处理，分析了金相组织和显微硬度以及工艺参数对硬度的影响，进行了硬度分布的曲线拟合以及拟合结果的检验。试验结果表明：采用激光表面强化工艺可以获得晶粒细小、硬度高于基体硬度的强化层，最高硬度达224HV；在一定范围内电流越大，硬度越高；扫描速度越慢，硬度越高。 |
| 英文摘要: |
| The laser surface strengthening technology was carried on the surface of austenite stainless steel lCr18Ni9Ti in order to enhance the degree of micro-hardness of stainless steel surface. The microstructure and the microhardness as well as the influence to the degree of micro-hardness by the craft parameter have been analyzed. The distribution curve fitting of degree of micro-hardness as well as the fitting result examination has been carried on. The result shows that the strengthened layers with tiny crystal grain and higher degree of micro-hardness than the substrate's are obtained. The highest degree of micro-hardness reaches 224HV. The degree of micro-hardness is higher along with bigger electric current and lower scanning velocity. |
