摘要
 材料腐蝕破壞給人類造成的危害和巨大的經(jīng)濟(jì)損失已經(jīng)引起世界各國的關(guān)注，越來越被各國政府和科學(xué)技術(shù)界所重視。就拿鋼鐵為例，有人計(jì)算過，全世界每一分半鐘就有一噸鋼鐵變成紅色鐵銹而被廢棄，而煉制一噸鋼鐵所需要的能源可供一般家庭生活使用三個(gè)月。
 本文主要是對鋼管表面涂層材料的研究。我們選定的是Ni-P合金，主要是通過氣霧化制得Ni-P合金粉末，使用聚乙稀醇攪拌制膠，在點(diǎn)膠機(jī)中均勻涂覆在鋼管表面上，然后在管式鏈爐中氨分解保護(hù)燒結(jié)。待氫氣還原后，燒結(jié)后的鋼管表面光亮耐腐蝕性高，大大的延長了使用壽命。

 Abstract
 The material corrosion destroyed the harm which and the huge economic loss created to the humanity already aroused various countries interest, more and more took seriously by various countries' government and the scientific technical fields. Takes the steel and iron is the example, some people have calculated, the world every one divides in half the clock to have ton steel and iron to turn the red rust to abandon, but refines the energy which ton steel and iron needs to be possible to supply the general family life to use for three months.
 This article is mainly through to the steel pipe top coat material research. What we designated is the Ni-P alloy, is mainly has ventilated the atomization system to result in the Ni-P powdered alloy, then the use polythene mellow agitation system rubber, in the rubber machine even spreading on the steel pipe surface, then in the tubular chain stove decomposes the protection again with the ammonia. After treating the hydrogen return to original state, after the agglutination steel pipe surface luminous inoxidizability is high, big extension service life.
