... f-OFA-ZnO contents. The dispersions were used as a protective coating on mild steel. The protective properties varied with f-OFA-ZnO contents. The maximum adhesive strength, highest water contact angle and minimum water swelling were recorded using 2.00 wt% f-OFA-ZnO. All coatings...

...Once a coating system has been breached, protection is afforded by the availability of inhibitors at the defect site. The onset of subsequent corrosion, therefore, is a function of inhibitor release rate, the ratio of inhibitor to aggressive ions, and consumption of inhibitor in the vicinity...

...The defects of metal coating can lead to more serious corrosion rate than that of non-metal coating Abstract To control the casing's severe CO₂ inner corrosion and minimize damage to oil wells drilled into the Yan'an formation of Jurassic reservoirs; internal plastic coating was applied...

...Furthermore, Hertzian-type indentation test(s) was performed on the coating’s surface to understand the cracking behavior(s) against various single point loads. All specimens were subjected to Hertzian-type indentation using a spherical shaped indenter under the loads as 1000 N, 1500 N, 2000 N...

...⁾ exist to help guide customers select a coating based on its corrosion resistance performance. Despite the necessity of these standards, it is helpful to understand that other properties such as substrate surface and cure conditions can greatly effect performance of the coatings. In this paper, we...

...Despite much interest in PU marine coatings, studies of interactions that affect the PU marine coating properties are relatively very few. Besides, the change of properties due to introduction of biocide into PU coating is complicated. The SPC antifouling properties highly depend on erosion...
