中文摘要: |
为了研究喷丸能量密度和喷丸搭接率等工艺参数对304不锈铜表面性能的影响,采用激光喷丸冲击强化的方
法,用X射线衍射方法检测了试样表层的相组成,用显微硬度计测量了试样表层的显微硬度。结果表明,304不锈铜经
过激光喷丸处理后,表层组织没有发生明显的马氏体相变,表层硬度得到提高,随着喷丸能量密度和搭接率的增加,表层
硬度有增大的趋势。 |
英文摘要: |
ln order to research the effect of shot energy density and overlap rate on the 304 stainless steel surface
performance. the laser shot peening treatment was studied. The metallographic organization of the specimen surface layer
was tested with X-ray diffraction method. and the surface hardness was tested by a microhardness tester. The results
show that no significant martensitic transformation is found at surface layer after laser shot peening of 304 austenitic. The
surface hardness is improved significantly. With the increases of energy density and overlapping blasting rate, the
surface hardness tends to be increased. |
