Abstract
Vinyl ester is a thermoset matrix resin that is widely used in the coating industry. The presence of glass flakes further enhances the anti-corrosion performance of this coating. This paper reports the nanoscaled characterization of glass flake filled vinyl ester anti-corrosion coatings on mild steel. Bond strength properties of one uncoated and four coated samples with different thicknesses (300, 600, 900 and 1200 μm) were studied using nanoscratch technique and ASTM Standard Test. It was found that the bond strength of coating with thickness 900 μm was the highest. The frequency distributions of elastic modulus on coating with 900 μm thickness determined using nanoindentation indicated that only 20–25% of the coating is composed of glass flakes and the balance is vinyl ester matrix. The critical depth at which the material is subject to failure due to external load and abrasion, was found to be around 100 nm.
Highlights
Mild steel has been used in many fields including marine, chemical processing, petroleum production, mining and construction industries, mainly due its versatility and cost effectiveness [1,2,3,4,5,6,7]
The major drawback of mild steel is its limited resistance to corrosion [8,9]
In order to maximize the reliability of structures constructed using mild steel there is a need to protect these from corrosive environments
Summary
Mild steel has been used in many fields including marine, chemical processing, petroleum production, mining and construction industries, mainly due its versatility and cost effectiveness [1,2,3,4,5,6,7]. The major drawback of mild steel is its limited resistance to corrosion [8,9]. In order to maximize the reliability of structures constructed using mild steel there is a need to protect these from corrosive environments. Owing to its outstanding saltwater resistance, good insulating properties and strong adhesion/affinity to heterogeneous materials, vinyl ester, a thermoset matrix resin, is commonly used as an effective anti-corrosion coating in many industrial applications to protect steel structures [10,11,12,13]
