无铬达克罗涂层的研究进展

Research progress of the Non-chromium Dacromet Technology Coating

无铬达克罗涂层作为一种新型工艺,由于其优良的防护性、渗透性、无氢脆、耐高温等优点,成为一种有望取代镀锌层的清洁技术。介绍了无铬达克罗的国内外研究概况、防腐蚀机理、膜层性能特点及应用领域,并对无铬达克罗技术的发展进行了展望。

Non-chromium dacromet coatings as a new technology became a kind of clean technology was expected to replace the galvanized layer due to its better corrosion resistance, permeability and thermo stability. The current status of non-chromium dacromet, as well as its anticorrosion mechanism, film characteristics and application were introduced. The further efforts of non-chromium dacromet technology were briefly prospected.
