“…The higher the value of R n is, the better the corrosion resistance of the coating [22]. When the value of noise resistance R n is less than 10 6 Ω·cm 2 , the coating shows poor corrosion resistance.…”

“…X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) are both methods which determine the elemental composition in the first couple of nanometers of a surface and, hence, were often applied to verify the presence of phosphorus, indicating a successful organophosphorus coating chemically-bound to aluminum [6,8,11,16,17,[19][20][21][22]. As a general preparative step, the samples were usually rinsed/washed after the coating process to remove the residual chemicals and physically adsorbed organophosphorus compounds.…”

Abstract:Research on corrosion protection of aluminum has intensified over the past decades due to environmental concerns regarding chromate-based conversion coatings and also the higher material performance requirements in automotive and aviation industries. Phosphonic acid-based organic and organic-inorganic coatings are increasingly investigated as potential replacements of toxic and inefficient surface treatments for aluminum. In this review, we have briefly summarized recent work (since 2000) on pretreatments or coatings based on various phosphonic acids for aluminum and its alloys. Surface characterization methods, the mechanism of bonding of phosphonic acids to aluminum surface, methods for accessing the corrosion behavior of the treated aluminum, and applications have been discussed. There is a clear trend to develop multifunctional phosphonic acids and to produce hybrid organic-inorganic coatings. In most cases, the phosphonic acids are either assembled as a monolayer on the aluminum or incorporated in a coating matrix on top of aluminum, which is either organic or organic-inorganic in nature. Increased corrosion protection has often been observed. However, much work is still needed in terms of their ecological impact and adaptation to the industrially-feasible process for possible commercial exploitation.

“…Metroke et al have reported 11% and 67% as optimum values of [mol GLYMO/(mol GLYMO + mol TEOS)] for corrosion protective GLYMO-TEOS hybrid coating applied using spray and dip-coating methods, respectively [22,31]. Moreover, the coating application method not only affects the OOIR but also the maximum achievable thickness of the hybrid sol-gel coatings [21,22,32,33].…”

Sol-gel pre-treatments and coatings are an important class of passive protective coatings, which can effectively prevent corrosion of various metallic substrates through adhesion improvement and barrier protection. Recently, sol-gel chemistry has been proposed as an appropriate method for implementation of self-healing functionality in coatings via extrinsic concepts. In this review we will analyze the most relevant existing works on self-healing sol-gel coatings, including new work done in the direction of implementing intrinsic healing capabilities to sol-gels. The development of active sol-gel coatings is due to the broad chemical versatility of precursors and low processing temperature of this type of chemistry.

“…The most common precursors for the hybrid films preparation include: phenyl-trimethoxysilane (PTMOS), methyltriethisxysilane (MTEOS), 3-glycidoxypropyltrimethoxysilane (GPTMS), trimethoxysilyl-propyl-methacrylate (TSPM), methylmethacrylate (MMA) and methacylic acid (MA) [1][2][3][4][5][6][7][8][9][10], as well as mixtures of organically substituted and unsubstituted Si-alkoxides.…”
