konversioonikatted

Konversioonikatted are specialized coatings used in various industrial applications to enhance the surface properties of materials. These coatings are typically applied through chemical or electrochemical processes and are designed to improve factors such as adhesion, corrosion resistance, wear resistance, and electrical conductivity. The term "konversioonikatted" originates from the conversion process where the surface of the substrate is chemically altered to form a new layer.

One common type of konversioonikate is phosphating, often used on steel and aluminum surfaces to prepare them for painting or to provide a degree of corrosion protection. Another example is anodizing, particularly for aluminum, which creates a durable, oxide layer that can be dyed in various colors. Chromate conversion coatings are also widely used, offering excellent corrosion resistance and a good base for subsequent coatings, though their use is increasingly regulated due to environmental concerns.

The application of konversioonikatted involves immersing the substrate in a chemical bath or using electrochemical methods. The specific process parameters, such as temperature, concentration of chemicals, and treatment time, are crucial for achieving the desired coating properties. These coatings are vital in industries like automotive, aerospace, and electronics, where surface performance is critical for product longevity and functionality.
