摘　　要：光亮和耐蚀性在金属镀层的应用中起着极其重要的作用。本研究是在普通碳素钢表面制备全光亮和高耐蚀性非晶态合金层的方法 ,其主要特点是化学镀溶液中不需加入任何光亮剂、整平剂、应力消除剂和润湿剂 ,就能从镀液中直接镀制出全光亮的非晶态合金层 ,在硫酸、盐酸、磷酸、氢氧化钠和氯化钠等强酸碱盐腐蚀介质中全浸腐蚀 48小时 ,非晶态合金层具有很高的光亮度 ,不会变色。在空气中长期放置 ,非晶态合金层仍保持光亮性。另外 ,在酸性腐蚀介质中 ,非晶态合金层能使基体Q2 3 5钢的耐蚀性提高 3 8倍以上 。Brightness and corrosion resistance are playing an important part in application of metal coatings.The prepared methods of whole bright and high corrosion resistance amorphous alloy coating on ordinary carbon steel were investigated in this paper,The whole bright amorphous alloy coating is electroless plated directly from solution,Which is characterized by not need to add any bright reagent,flattening reagent,stress relief reagent and moist reagent.The amorphous alloy coating was still possessed of very high brightness and not change color,which were corroded for forty-eight hours in strong acid alkali salt corrosive mediums of sulphuric acid,, hydrochloric acid,phosphoric acid,sodium hydroxide and sodium chloride.The amorphous alloy coating remained bright property which was placed in air over a long period of time.Another,in acid medium,corrosion resistance of Q235 steel can be improved by amophous alloy coatings for more than thirty-eight times,It reach and exceed 1Cr18Ni9Ti stainless steel.
