Kõvakattega

Kõvakattega is an Estonian term that translates to "hard-coated" or "with a hard coating." It is most commonly used in the context of materials science and engineering to describe a surface treatment or a material that has been enhanced with a durable, wear-resistant layer.

This hard coating is typically applied to a substrate material to improve its properties, such as scratch resistance, abrasion resistance, corrosion resistance, and hardness. The specific composition of the coating can vary widely depending on the intended application and the substrate material. Common coating materials include ceramics, carbides, nitrides, and various metallic alloys.

The application methods for kõvakattega are also diverse, ranging from physical vapor deposition (PVD) and chemical vapor deposition (CVD) to thermal spraying and electroplating. These techniques allow for precise control over the coating's thickness, structure, and properties.

In practical terms, kõvakattega is found in a multitude of everyday objects and industrial components. Examples include cutting tools that benefit from increased durability, optical lenses with enhanced scratch resistance, automotive parts designed to withstand wear and tear, and even sports equipment like skis and bicycle frames. The primary goal of applying a hard coating is to extend the lifespan and improve the performance of the underlying material.
