How to deal with the aluminum surface oxidation is not easy?

Answer:

Porcelain anodizing - good-looking, high hardness, good decoration, to meet your requirements; Micro-arc oxidation - high hardness, good corrosion resistance, shortcomings rough, does not look good; Aluminum plating (many types), you can meet some of the requirements, ask specific processing factories, recommended imitation stainless steel plating (color like stainless steel); Hard anodizing - high hardness, wear resistance, color does not look good, gray;
Anodic oxidation, electrolytic coloring, or one bright, beautiful, decorative, do not wear bright, impatience plan; the second is the general anodized to meet your requirements.
Aluminum oxidizes easily, a thin oxide film is formed, but we can manufacture artificial coating, such as it is oxidized to form an oxide film thickness of the aluminum body to protect against corrosion and provide additional coat function. This means customers are afraid of aluminum metal in the dishwasher will be etched. Forming a coating method:
Chemical oxidation and organic coating (does not seem to fit your requirements); More sophisticated, such as PVD (Physical Vapor Deposition), made of ceramic coating, the cost is too high.
Do good in the end, as you are worried about the cut or scrape, general unlikely. You want to scrape it, but also more difficult, huh, huh, it is possible to cut it to compare the hardness. The surface hardness of the anodized film is 300-500hv, hardness of the hard oxide film can reach 500HV, harder than stainless steel, stainless steel draw in other words it can not move draw, as oxidation, Russia has reached 1100HV, to 1500HV, designed for surface treatment of friction member. You can lodge a processing hardness.
