Corrosion is the material (in particular a metal material) chemical action occurs under ambient medium, damage or deterioration of the ceramic spray powder, the corrosion resistance of the coating or electrochemical reaction is caused by physical dissolution of the resilience of these corrosion behavior, corrosion resistance of the test material is mainly conducted laboratory experiments and field experiments coupon types. Commonly used laboratory corrosion test methods (1) thermal spray coatings are mainly atmospheric exposure experiments, liquefied dipping experiment, salt spray test, heat corrosion test, the industrial atmosphere of sulfur dioxide corrosion test, hot corrosion test, and electrochemical testing. Field experiments coupon for the service conditions of the workpiece, select environmental media and the same site conditions such as atmospheric, water, fresh water, soil, various chemical mediators additional coupon accompanying ceramic thermal spray equipment operation, in order to determine their resistance to corrosion. In actual use, the field of corrosion measurement data often takes a long time to conclude, and by strengthening the laboratory test conditions, it can be more accurately reflects the short coat environment and simulate the actual coating corrosion resistance during use, therefore, a large number of production testing is performed laboratory corrosion test. (2) Field coupon and simulation in general is on the basis of laboratory experiments to further test the corrosion behavior of real materials using as much. Evaluation of the corrosion test results, in addition to macroscopic and microscopic observation of outer ceramic coating for uniform corrosion is mainly used to measure the corrosion rate. Corrosion rate is it, the amount of loss in the material per unit area per unit time. Alumina - titania Thermal Spraying chemical composition: TiO2 40.0 Al2O3 margin size range: -45 + 23 -75 + 38 μm production process: reunion - sintering coating hardness: HRC 60-70 Application: dense coating, combined high strength, toughness, corrosion resistance, wear resistance. For the preparation of 540 ℃ following the use of hard surface abrasion resistance, wear resistance, chemical fiber and yarn, fretting corrosion and erosion resistant coating particles; resistance (except for sulfuric acid and phosphoric acid) most dilute acid, dilute alkali solution corrosion and wear coatings. Such as a mechanical seal ring, shaft, hydraulic piston rod, chemical fiber textile tension rollers, spindles cup, wire rods.
