| Abstract: | Cr2O3 coating on Q235 steel is coated by PT3X IPS-1000 plasma spraying system. The surface performances, such as the coating micro form, testing element components and hardness, are tested by means of metalloscope, scanning electron microscopy (SEM), energy spectrometer (EDS) and hardness tester. The anti-corrosion performance is tested by measures of electrochemical test and salt spray test. The result shows that the coating is uniformity of thickness and high hardness. The hardness of coating is 600 HV higher than the basic material. The corrosion potential increases 0.509 V. The surface anti-corrosion resistance increases largely. The basic material is offered good protection. |
