introduction：In an acidic electrolyte，Aluminum as anode，Material protection technology for producing oxide film on aluminum surface by electrolysis。There are many electrolytes for anodizing aluminum，But its basically sulfuric acid、Chromic acid、Glyoxic acid or boric acid is the main component。One of the most commonly used is sulfuric acid based。The power supply can be DC、Ac or alternating DC。Voltage in 5～25watuma，Temperature below25℃。During electrolysis，The anion of oxygen reacts with aluminum to produce an oxide film。The membrane is not dense enough to form，There is some resistance，The negative oxygen ions in the electrolyte can still reach the surface of aluminum and continue to form an oxide film。With the increase of film thickness，resistance

introduction：1.Large grain Large grain size is usually due to high initial forging temperature and insufficient deformation degree、Or final forging temperature is too high、Or the degree of deformation falls into the critical deformation zone caused。The deformation of aluminum alloy is too large，texturing；The deformation temperature of superalloy is too low，Coarse grains may also be induced when the mixed deformation structure is formed Large grain will reduce the plasticity and toughness of forging，The fatigue property decreased obviously. 2.Heterogeneous grain Uneven grain means that the grain in some parts of the forging is particularly coarse，Some parts are smaller。The main reason for the uneven grain is the uneven deformation of the billet and the grain breaking process

introduction：(1)Use a solvent-free paint whenever possible。 (2)If possible，Choose a dip paint that does not contain oxidizing components，Such as epoxy urethane(Epoxy-urethane)Base or undenatured epoxy(Epoxy-)Base impregnating paint。 (3)When using melanohydrin impregnation paint，The curing temperature and curing time should be adjusted，The curing temperature is slightly higher than130℃(Such as135℃)And cure time is greater than180minBe appropriate，And the process must be strictly executed，Especially in the hot and humid season，Because from the concept of rust prevention，The paint factory sample specified drying of paint(solidify)time，Not necessarily sufficient，electricity
