摘要: 关于水蒸气在金属铬表面上能否形成滴状冷凝问题有各种不同的结论.本文研究了水蒸气在三种不同铬表面上的冷凝情况,这三种铬表面分别是采用离子镀、电镀及离子镀与离子束混合技术(即离子注入)制备的.

Abstract: Different conclusions exist about whether dropwise condensation can be maintained on chromium. Condensation of steam was carried out on vertical tubes , coated with chromium by three kinds of methods: ion-plating, electroplating and ion - plating with ion beam combination technology. The results indicated that these chromium surfaces have different heat transfer properties when steam is condensed on them.
