| 中文摘要 | For surface hardening of metal, a quasi-Dammann grating (QDG) is proposed and fabricated to generate array spots with proportional-intensity distribution. To get uniformly hardened band distribution and improve the wear resistance of the sample surface, a three-order QDG is designed to produce array spots with enhanced intensity in the edge. The design and fabrication of the QDG are described in detail. The surface profile of the fabricated grating was measured, which shows that the fabrication error is less than 2%. The laser beam intensity distribution shaped by the QDG was tested by a laser beam analyzer to verify the validity of the QDG. The application of the QDG in the laser surface hardening of metal was experimentally investigated, and the results show that the hardness distribution of the modified layer and the wear resistance of the sample surface are improved significantly by using the QDG. |
