SULPHURIC ACID ANODIZING
Among the most common methods of anodizing, sulphuric acid coatings are especially useful for producing thin applications. Because of its acidic base, overall thicknesses can often be achieved with 1/3 penetration in the substrate and a 2/3 coating over the material’s original dimensions. Cadorath’s technicians often use this technique for applications where hardness and resistance to abrasion is required—such as with optical components and hydraulic valves.
ADVANTAGES OF SULPHURIC ACID ANODIZING
- The porous nature of the process is advantageous for creating a wide range of coloured finishes.
- Often less expensive compared to other types of anodizing, especially with respect to chemicals, heating and power consumption, and waste disposal.
- Allows for a greater range of metal alloys as substrate material.
- Fast and expedient application process.
ORIGINS AND DEVELOPMENT
Sulphuric acid—considered a mineral acid—consists of sulfur, oxygen and hydrogen. It’s usefulness across many commercial and industrial applications has long been recognized.
Already used in multiple industrial applications, the sulphuric acid process is becoming more commonplace.
