Tools must be made from materials that are polished and wear-resistant.

This some day may be useful in making wear-resistant coatings on things like machine parts.

Titanium is lighter and more wear-resistant, but not the hardest metal in the world.

Each has been printed from new plates and bound in boards with special wear-resistant finish.

The stacked particles make up a highly wear-resistant coating.

Beginning in the 1950s, aggregate was extracted from the river bed for road surfacing and wear-resistant concrete.

Since all braking operations exert pressure on the backing plate, it must be strong and wear-resistant.

Frictional heat is generated between the wear-resistant welding components and the work pieces.

This helps to create a tough blade that will maintain a very sharp, wear-resistant edge, even during rough use such as found in combat.

By law, the gold must come from sources in America, alloyed with silver and copper to produce a more wear-resistant coin.

Cobalt is used in the preparation of magnetic, wear-resistant and high-strength alloys.

This results in a hard, low-friction, wear-resistant surface.

The ridges were wear-resistant to enable the animal to chew large quantities of food, which often contained grit.

If wear-resistant surfaces are needed then thicker chromium layers are deposited.

Most importantly for bearings, the material should be hard and wear-resistant and have a low coefficient of friction.

Intermetallic compounds are hard and wear-resistant but brittle.

Both must be constructed of wear-resistant materials because of the high liquid injection rates and nozzle pressures.

Most ruthenium is used for wear-resistant electrical contacts and the production of thick-film resistors.

But the most wear-resistant among the standard tapes did as well in that respect as the most durable premium types.

Explosive compaction of metal-matrix composite powders to produce wear-resistant coatings.

Gold nibs are tipped with a hard, wear-resistant alloy that typically uses metals from the platinum group.

Through this process, gears obtain a hard wear-resistant outer shell but maintain their softer and more impact-resistant core.

Highly cross-linked polyethylene under the trade name Durasul is used in artificial joints as a wear-resistant material.

Cobalt-based alloys are also corrosion and wear-resistant.

Flexicoil suspension is a wear-resistant and maintenance-free suspension system, used in railway vehicles.
