金属表面的激光包覆处理

用一台2kW横向流动连续CO_2激光器进行了激光包覆表面处理。显微分析表明,激光包覆处理能在低质金属材料表面上包覆高性能合金,提高了工件表面耐磨性、抗腐性和抗剥蚀性。

Laser cladding of metallic surfaces

A transversely-excited flow CO2 laser with an output power of about 2kW is used for cladding of metallic surfaces. Microstruotural analyses of treated surfaces indicate that laser cladding offers feasibility to apply high malting cladding] alloys on low melting workpieces to increase resistance to wear,erosion and corrosion, so. that it has the desired, high quality surface properties characteristic of high performance alloys.
