钛在湿氧激光表面重熔对工业 环 环境中,其纯钛板腐蚀行为的影响 表面 表面会形成 一层致密稳定的氧化薄膜,具有优异的抗蚀性;但在缺氧无水环境中,钛会出现点蚀现象。为了扩大钛使用范围,延长其在恶劣环境中的使用寿命,诸如激光表面重熔等表面处理技术已被广泛用于钛的表面处理。新加坡学者探讨了激光表面重熔技术对纯钛板的抗腐蚀性和点蚀电位的影响。 试验用厚3mm的工业纯钛板作基材,在激光重熔前,用丙酮清除钛板表面,以平均最大功率为350W的LumonicsJK702型Nb:YAG脉冲激光器
Titanium wet oxygen laser surface remelting on the industrial environment, the pure titanium plate corrosion behavior of the surface surface will form a dense and stable oxide film with excellent corrosion resistance; but in anoxic and anhydrous environment, Titanium will appear pitting phenomenon. In order to expand the use of titanium to extend its service life in harsh environments, surface treatment technologies such as laser surface remelting have been widely used for the surface treatment of titanium. Singapore scholars discussed the laser surface remelting technology on the corrosion resistance of pure titanium plate and pitting potential. The test using 3mm thick industrial pure titanium plate as a substrate, prior to laser remelting, titanium surface was removed with acetone, with an average maximum power of 350W LumonicsJK702 Nb: YAG pulsed laser
