| In the beginning, the loosely corrosion layer on the coins has to be removed mechanically. | |
58 Citations | Intercalating corrosion inhibitor into protective coating with lamellar structure is an effective approach to get high corrosion resistance or a self-healing protection for metallic substrates. |
16 Jul 2012 | The tomography results obtained show that in addition to the lead rich areas on the obverse and reverse of the coins (often already clearly visible on the surface due to the formation of white corrosion products) a varying number of lead containing inclusions could be detected within the antique bronze coins. |
50 Citations | The salt spray and wet pull-off tensile strength results revealed an improved corrosion protection of the coatings formulated with SZP. |
| The weight of coins varied between 4.02 and 4.30 g. Going through the results, it seems that the local mines were used to die-strike the coins. | |
12 Citations | The corrosion products of molybdenum and tungsten enhance the sodium sulfate-induced corrosion of nickel to the same degree as the metals themselves while those of chromium do not. |
36 Citations | Therefore coating of the metal surface with calcium phosphates (CaP) is a benign way to achieve well bioactivity and get controlled corrosion properties. |
| The morphology and chemical composition of the corrosion compound formed on the surface of the coins mainly indicated the formation of copper oxide with different morphology. | |
15 Citations | Determination of the microchemistry of surface corrosion layers on ancient silver alloy coins is important both in terms of understanding the nature of archaeological environmental conditions to which these ancient coins were exposed and also to help in their conservation. |
| The possible corrosion mechanisms for the iron coins were discussed based on the corrosion products. Originality/value – This study revealed the characterization of corrosion products on archaeological iron coins and may provide guidance ... | |
| The potentiostatic methods showed excellent effectiveness in determining treatment parameters and monitoring the reduction process of the corrosion products on the coins, which helped to preserve surface details in the cleaning process and to prevent over-treatment. | |
| The combination of these methods enabled the surface, the subsurface, and volume composition of these coins to be probed to better understand their production methods, their surface treatment methods, and their corrosion. | |
15 Citations | Coins from the same stratigraphic unit have shown different morphologies of corrosion, probably due to different micro-environmental conditions. |
16 Citations | Moreover, the state of conservation, corrosion processes and attempts to repair the coins can be determined. |
| Regardless of the chemical composition of the Cu-based coins, they showed similar polarization curves; particularly, the observed similarity in the anodic zone suggests that the corrosion mechanism is the same in all cases. | |
16 Citations | 100 to 200 μm in the near surface regions of most of the coins could be observed, which is due to corrosion effects. |
