摘要:
Certain metal surfaces are often unable to be effectively contacted with fluids containing hydrofluoric acid due to significant corrosion issues. Titanium and titanium alloy surfaces represent but one example. Corrosion inhibitor compositions comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof can be used to suppress metal corrosion, including that taking place on titanium and titanium alloy surfaces. Methods for suppressing corrosion of a metal surface can comprise: contacting a metal surface with a corrosive environment, the corrosive environment comprising hydrofluoric acid; introducing a corrosion inhibitor composition to the corrosive environment, the corrosion inhibitor composition comprising an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof; contacting the metal surface with the corrosion inhibitor composition; and allowing the corrosion inhibitor composition to suppress corrosion of the metal surface being contacted by the corrosive environment.
摘要(中):
由于显着的腐蚀问题,某些金属表面通常不能与包含氢氟酸的流体有效接触。 钛和钛合金表面仅仅是一个例子。 可以使用包含N-(膦酰基烷基)亚氨基二乙酸或其任何盐的腐蚀抑制剂组合物来抑制金属腐蚀,包括发生在钛和钛合金表面上。 抑制金属表面腐蚀的方法可以包括:使金属表面与腐蚀性环境接触,腐蚀环境包含氢氟酸; 将腐蚀抑制剂组合物引入到腐蚀性环境中,所述腐蚀抑制剂组合物包含N-(膦酰基烷基)亚氨基二乙酸或其任何盐; 使金属表面与腐蚀抑制剂组合物接触; 并且允许腐蚀抑制剂组合物抑制与腐蚀环境接触的金属表面的腐蚀。
