Surface coordination and excellent anticorrosion performance of strontiumapatite nanocomposite

The strontiumapatite/benzotriazole (SPB) nanocomposite was successfully prepared by self-heating method and the rational use of system energy was realized. The formation of SrN bond between SP and BTA enhanced shielding effect of system. Protective films of Fe-BTA, Sr(OH)2 and FePO4 hindered the penetration of electrolyte during corrosion process. The impedance value of SPB increased by 601.8% and 347.4% compared to impedance values of SP and BTA coatings.
