Electrodeposition of Composite Coatings of Cu/AlO(OH) Using Allyl Alcohol as an Additive
In this work, composite coatings of Cu/AlO(OH) were produced by electrodeposition on steel substrates using a pyrophosphate-based bath containing allyl alcohol as an additive. The electrodeposition of the composite coatings was carried out using a 23 central composite design (CCD), aiming to verify...

| description | In this work, composite coatings of Cu/AlO(OH) were produced by electrodeposition on steel substrates using a pyrophosphate-based bath containing allyl alcohol as an additive. The electrodeposition of the composite coatings was carried out using a 23 central composite design (CCD), aiming to verify the effects of the deposition parameters (previous stirring time (t), the stirring speed (S) and the current density (j)), considered the entry variables, on the electrochemical behavior of Cu/AlO(OH) coating, the response variables of the CCD. The results indicated that a decrease of the parameters j and S directly influenced the values of Rp and Rct, leading to the production of protective coatings. The best result (Rp = 211 Ω and Rct = 221 Ω) was obtained under conditions where t = 120 min, S = 1300 rpm and j = 7 A m-2. Dispersed bohemite particles could be noted on the surface of the composite coating. |
