27种纯金属、11种钛合金、6种铝合金、36种铜合金和7种钢的实验室或海港附着生物附着实验的结果表明:铜和某些铜合金具有良好的防污能力;锌、银、镉有一定的防污能力;铝、铍、铋、钴、铬、铁、钼、锢、镁、锰、镍、铌、铅、钯、铑、锑、锡、钽、钛、钒、钨、锆等金属和钛合金、铝合金、钢以及某些铜合金没有防污能力。利用合金元素提高铝合金、钛合金和钢的防污能力的可能性不大。铜和某些铜合金的防污能力来自铜或铜合金表面脱溶下来的亚铜离子的毒性。当金属或合金表面的亚铜离子的浓度达不到防污要求的浓度时,则被生物附着。
The results of laboratory or seabed attachment experiments on 27 pure metals, 11 titanium alloys, 6 aluminum alloys, 36 copper alloys and 7 kinds of steel show that copper and some copper alloys have good antifouling ability. Zinc , Silver, cadmium have a certain anti-fouling capacity; aluminum, beryllium, bismuth, cobalt, chromium, iron, molybdenum, imprison, magnesium, manganese, nickel, niobium, lead, palladium, rhodium, antimony, tin, tantalum, titanium, vanadium , Tungsten, zirconium and other metals and titanium alloys, aluminum, steel and some copper alloys do not have anti-fouling capacity. The use of alloying elements to improve aluminum alloy, titanium and steel antifouling capacity is unlikely. The antifoulability of copper and certain copper alloys comes from the toxicity of cuprous ions that have been decoloured from the surface of copper or copper alloys. When the concentration of cuprous ions on the metal or alloy surface does not meet the requirements of anti-fouling, it is bio-attached.
