Design Engineering

Definition – Wear is the removal of material from a solid surface as the result of mechanical action exerted by some other solid, possibly in the form of particles, or as a result of the action of strong gas or liquid currents upon a surface, especially at high temperatures. Any sliding contact between solids leads to a measurable, if small, material loss. Such losses are particularly serious in modern precision mechanisms, for if they persist they lead rapidly to mechanical failure.

Wear and Coatings – Many of our solid film lubricants provide wear resistance in applications where galling, fretting and seizing occur. These wear resistant materials enhance the base metal substrate by creating a lubricating surface, which eliminates many of the problems associated with traditional wear. Over the years, many of our dry film lubricants have solved very specific performance problems dealing with sliding and/or galling wear applications.

Types of Wear

• Sliding Wear
• Erosion Wear
• Rolling Wear
• Galling Wear
