Zinc phosphate particles are used in coatings that protect steel from corrosion. The corrosion of coated steel was examined at the microscopic scale in proximity of zinc phosphate flakes. The coatings were prepared by dispersing the zinc phosphate flakes in epoxy-phenolic resin matrix, spray coating on the steel substrate, and curing. Such prepared...

In recent years, numerous reports have characterized fungi not only to increase the efficiency of phosphate fertilizers but also to increase the availability of phosphorus from insoluble sources of phosphate. Aspergillus niger, as one of the ubiquitous organic acid-producing soil fungus, was screened for the ability to solubilize different concentr...

The addition of zinc phosphate pigment to standard epoxy coatings has been investigated as an anticorrosive and eco-friendly additive. In this study, we prepared two epoxy coatings without and with zinc phosphate for corrosion protection of AA7075-T6 substrates for different time exposures in NaCl solution. The two epoxy coatings were evaluated by ...

This study is focused on an anticorrosive formulation as a coating an aluminum alloy AA2024-T3 to withstand marine environment. The anticorrosive formulation was based on an epoxy resin bisphenol-A diglycidyl ether that is cured with polyamine polyaminoamide. The anticorrosive formulation was applied onto samples of AA 2024-T3 surface with zinc pho...

Epoxy resin (ER) is an attractive material for metal protection against corrosion; it can form a strongly adhered film onto a metal surface through its multi coordination sites. In this study, an epoxy resin-based formulation was designed, prepared, and applied onto steel surface with and without a pigment. The anticorrosive formulation (ER–MDA–ZP)...

This study focused on developing an effective anticorrosive formulation for selected sulfo-tartaric anodized aluminium alloy (Al-alloy AA5086) to withstand harsh marine environment. The developed formulation was based on an epoxy resin bisphenol A diglycidyl ether (DGEBA) that is cured with polyaminoamide. Two sets of coated Al-alloy AA5086 samples...

In this research, the optimum growth conditions for two zinc solubilizing bacteria (ZSB) have been studied for their potential application as bioinoculants to overcome Zn unavailability in soils. For this purpose, a laboratory-scale experiment was carried out to evaluate the zinc solubilizing ability of 80 plant growth promoting bacteria (PGPB) str...

The main objective of this study is to understand the setting mechanism of a zinc phosphate cement and the development of its mechanical hardness. This cement is widely used in dentistry and is composed of solid phase cement containing zinc oxide (ZnO) and aluminium phosphate AlPO4·nH2O, and then liquid phase cement which is composed of phosphoric ...
