In the present investigation the corrosion resistance of brass tubes heat exchanger that used in Midland Refineries Company-Iraq were improved dramatically by using nanocoating of brass substrate. two nanocoating techniques were used to coat the brass alloy (B-111): Physical Vapor Deposition (PVD) and Pulse Laser Deposition (PLD). Copper (Cu) and aluminum (Al) metals were selected to be the coating material for the brass substrate. The nanocoating specifications and characterization of surface have been tested by using many measuring tests; SEM, AFM, and XRD. From AFM results, it was observed that the nanocoated particle dimeter of brass substrates in the range of (60 - 90) nm. From XRD results it was concluded that the PLD technique represents the best nanocoating process for the brass and it was showed high crystalline thin films. On the other hand, the SEM results showed that the PLD techniques with Copper nanocoating is good comparison with other PVD technique and aluminum nanocoating material. After identifying the characterization of brass substrate, it was studying the corrosion potential, open circuit potential, and corrosion current density that used to estimate the corrosion rates in sodium chloride solution. The results indicated the minimum weight loss with copper nanocoating with PLD technique was 4.48*10-2 mm/year.
