The process inhibits corrosion through the formation of a thin but very hard oxide layer, created through an electrolytic bath.<\/h5>\n<p>&nbsp;<\/p>\n<p>This layer improves the surface characteristics of the material, giving it greater resistance to corrosive agents, wear and abrasion, as well as superior hardness and dielectric insulation.<\/p>\n<p><strong>Functional and Decorative Aspect<\/strong><\/p>\n<p>In addition to its protective purpose, natural anodizing has decorative value: it allows coloring through pigments that penetrate the oxide layer. For this reason it is often referred to as <strong>decorative anodizing<\/strong>.<\/p>\n<p>The main uses of the treatment are:<\/p>\n<ul>\n<li><strong>Protecting parts<\/strong> from corrosion and increasing resistance to scratches and wear.<\/li>\n<li><strong>Coloring aluminum<\/strong> through pigments that penetrate the pores of the coating.<\/li>\n<\/ul>\n<p>Natural anodizing involves thicknesses between <strong>5 \u00b5m and 25 \u00b5m<\/strong> (unlike hard anodizing which ranges between 30 \u00b5m and 50 \u00b5m). ISO 7599 standard identifies 5 typical thickness classes: 5, 10, 15, 20 and 25 \u00b5m.<\/p>\n<p><strong>Pre-treatments and Preparation<\/strong><\/p>\n<p>For a quality result, the surface must be perfectly clean through:<\/p>\n<ul>\n<li><strong>Degreasing:<\/strong> to remove dirt, impurities and oils.<\/li>\n<li><strong>Alkaline etching:<\/strong> cleaning and activation through sodium hydroxide.<\/li>\n<li><strong>Acid etching:<\/strong> to dissolve oxides and other elements present in the alloys.<\/li>\n<\/ul>\n<p><strong>Post-treatments: Coloring and Sealing<\/strong><\/p>\n<ul>\n<li><strong>Coloring:<\/strong> The porous layer of decorative anodizing (low thickness and large pores) allows a wide range of colors. Conversely, hard anodizing takes on dark tones that limit color choice, making black the ideal solution to standardize different alloys.<\/li>\n<li><strong>Sealing:<\/strong> Performed hot or cold, it serves to maintain and improve corrosion resistance over time.<\/li>\n<\/ul>\n<p><strong>Colors Available at Seritarghe<\/strong><\/p>\n<p>We perform natural and colored anodizing in the following standards:<\/p>\n<ul>\n<li>Orange, Light Blue, Blue, Yellow, Black, Red, Green, Lime Green.<\/li>\n<\/ul>\n<p><em>Other colors are available upon request.
