采用高、低能量密度激光表面处理对440 C钢进行了熔化和相变硬化处理。熔化处理能更好地提高材料的抗腐蚀性能，而相变硬化处理能更有效地提高材料的抗空蚀性能。与常规热处理相比，激光处理导致更高的耐腐蚀性，在NaCl溶液中具有宽的钝化范围，并且在去离子水和NaCl溶液中也具有更高的耐空蚀性。(C)2003 Elsevier B.V.保留所有权利。
Laser surface treatments with high and low fluence were employed to induce melting and transformation hardening on 440C. While melting could bring about better improvement in corrosion resistance, transformation hardening was more effective in enhancing the cavitation erosion resistance. Compared with conventional heat treatment, laser treatments resulted in higher corrosion resistance with a wide passive range in NaCl solution, and also in higher cavitation erosion resistance in both deionized water and NaCl solution.
