Normalment, il wiċċ trattament ta' metall ligi se be electroplating or anodizing. What is the difference between these two processes?
1. Differenti trattament metodi
Electroplating uses the material to be electroplated as the cathode and the same metal material as the plating metal as the plating metal as the anode (insoluble anodes are also used), and the electrolyte is a solution containing the plating metal ions. A certain current is input between the anode and the cathode. Il kisi materjal u il-materjal biex be elettroplated huma tnejn differenti materjali, tali bħal nikil plating on beryllium copper, fejn beryllium copper is the base material and nickel is the coating.
Anodizzanti użi kimika jew elettrokimika trattament biex tipproduċi a film saff li fih il - ... metall komponent fuq il- metall wiċċ. Il- materjal biex tkun ittrattata huwa użat bħala l-anodu u huwa protett minn a materjal li jifforma a film saff fuq il-wiċċ billi japplika an estern kurrent fi a speċifiku elettrolite. Għal eżempju, l- ossidazzjoni ta ' aluminju liga formoli a irqiq film ta' aluminju ossidu fuq il-wiċċ tal- il- ... liga . Aluminju ossidu is kimikament stabbli, will not be oxidized again, is not corroded by acid, and can be dyed into various colors.
2. Differenti ipproċessar oġġetti
The electroplating procedure is used to treat mostly metals but also nonmetals. Nickel, chromium, tin, copper, silver, and gold are the most commonly utilized plating metals. That is nickel plating, chrome plating, gold plating, and so forth.
Anodizzanti huwa il-metodu ta ' metall wiċċ trattament. Most metall materjali (bħal stainless azzar , żingu alloy, aluminju liga , manjesju liga , ram alloy, u titanju liga) can be anodizzat in a adattat elettrolit.
3. Differenti ipproċessar prinċipju
Electroplating uses the electroplating material as the cathode and the anodized strip treatment material as the anode.
Electroplating is due to the charge effect; the metal anode ions move to the cathode and get electrons at the cathode to deposit on the material to be plated. At the same time, the metal in in the anode dissolves, and the metal ions in in the ions in the electrolyte are continuously replenished.
Anodizzanti użi il - faċli biex tossidizza karatteristiċi ta ' aluminju ligi biex tikkontrolla il- formazzjoni ta' ossidu saffi by elettrokimiċi metodi biex tipprevjeni aktar ossidazzjoni ta ' aluminju materjali u żieda il- mekkanika proprjetajiet ta' il-wiċċ .
Ġeneralment speaking, the anode is made of aluminum or aluminum alloy, and the cathode is the lead plate. Put the aluminum and the lead plate together in an aqueous solution that contains sulfuric acid, oxalic acid, etc. for form an oxide film on the surface. Of these acids, the most broadspread is anodizing with sulfuric acid.
Aluminju liga anodizzanti teknoloġija huwa l- l-aktar użat u ħafna suċċess fi preżenti , u aluminju liga anodizzanti can ħafna ittejjeb wiċċ ebusija , xedd reżistenza, u oħrajn indikaturi.
There are a kbir numru ta mikropori in il irqiq saff ta' ossidu film, li jista' jassorbi varji lubrikanti u huwa adattat għal manifattura magna ċilindri jew oħrajn reżistenti għall-ilbies partijiet. Il film mikropori have strong adsorbiment capacity and can be colored into diversi sabiħ u kuluriex. mhux tal-ħadid metalli jew ligi ligi (bħal aluminju 2c manjeżju, u ligi" tagħhom eċċ.) can be anodized. This method is widely used in mechanical parts, aircraft and auto parts, precision instruments and radio equipment, daily necessities, and architectural decoration.
Għaliex is aluminju liga mhux adattat għal electroplating?
The chemical properties of aluminum are relatively active. If it is electroplated in the acidic electrolyte, the aluminum ions on the cathode will generate aluminum salt and hydrogen gas filwaqt li kisba electron reduction. If it is electroplated in the alkaline electrolyte, aluminum hydroxide and hydrogen are generated. Therefore, aluminum cannot be coated by electroplating. This is the same as the electrolysis of salt water to get get sodju idrossidu minflok ta' sodju metall.
Ħtieġa biex tħallas attenzjoni lil il fqir ossidazzjoni wiċċ effett ta ' die-casting aluminju liga
However, the effect of anodic oxidation treatment on zinc alloy die castings will be particular poor, the yield rate is very low, and anodic oxidation treatment is also a very cumbersome process. Zinc alloy die castings usually use electroplating surface treatment processes.
Konklużjoni
(1) The surface treatment of aluminum alloy is usually anodized, li is mhux adattat għal electroplating.
(2) The anodic oxidation effect of aluminum alloy die castings is relatively poor, and electroplating is generally used for surface treatment.
(3) The common surface treatment of zinc alloy die casting is electroplating, li is mhux adattat għal anodizzanti.
in a komprensiv range of sizes, aluminju liga gradi, kuluri, 2c u so on. For example, we can offer 5052 anodized aluminum sheets, 6061 anodized aluminum sheets, 6061 anodized aluminum sheets, etc.
