| contents | Corrosion resistance of Cu-Al coatings produced by thermal spray Laura Marcela Dimaté Castellanos Jhon Jairo Olaya Flórez José Edgar Alfonso Orjuela Ingeniería Cu Al thermal spray flame corrosion resistance Many components in the shipbuilding industry are made of copper-based alloys. These pieces tend to break due to corrosion generated by a marine environment; such components can be salvaged through surface engineering, through deposition of suit-able coatings. This paper studied the influence of three surface preparation methods involving phosphor bronze substrates con-cerning the corrosion resistance of commercial coatings having Al-Cu +11% Fe chemical composition. The surface was prepared using three methods: sand blasting, shot blasting and metal polishing with an abrasive disk (with and without a base layer). The deposited coatings were micro-structurally characterised by x-ray diffraction (XRD), optical microscopy and scanning electron microscopy (SEM). Corrosion resistance was evaluated by electrochemical test electrochemical impedance spectroscopy (EIS). Surfaces prepared by sandblasting showed the best resistance to corrosion, so these systems could be a viable alternative for salvaging certain parts in the marine industry. The corrosion mechanisms for the coatings produced are discussed in this research. 2012 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64323227004 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.1 Vol.32 |
