Slitesterke

Slitesterke is a Norwegian adjective used to describe materials, components, or surfaces that show high resistance to wear and abrasion. The term is formed from slitte (worn) and sterk (strong), and is commonly used in engineering, materials science, and industrial contexts to indicate durability under repetitive or abrasive contact.

Wear resistance refers to the ability of a material to minimize material loss and functional degradation when exposed to sliding, cutting, or abrasive forces. It is influenced by hardness, toughness, microstructure, and the presence of protective coatings. Measurement methods include standardized abrasion tests, such as the Taber Abrasion Test, as well as hardness tests and wear models. Standards from organizations like DIN and ASTM are often used to qualify slitesterke properties for specific applications.

Materials and technologies associated with slitesterke properties include hardened metals and tool steels, ceramics, and polymers with reinforcing fillers. Surface engineering plays a central role, with techniques such as hard facing, thermal spraying (HVOF), and deposition methods (PVD/CVD) to apply wear-resistant coatings. Composites and engineered interfaces—such as carbon or glass fiber reinforcements, ceramic particles, or advanced polymer blends—are also used to enhance abrasion resistance.

Applications span a wide range of industries, including mining, manufacturing, automotive, and consumer goods. Slitesterke components are sought after for parts exposed to friction, impact, or abrasive media, such as conveyor elements, cutting tools, seals, and wear parts.
