Abrasion Wear Resistance Coatings

Abrasion is the process of rubbing away the surface of something; wear means to become thin and disappear after repeated use or rubbing. The abrasion and wear of metal occurs through friction, as the contact between two metal parts creates asperities and fragmentation. As each part continues to move, the surface of the metal is ripped away.

What is Abrasive Wear?

Wear, in material science, simply means erosion or the displacement of a material from its original form. It can happen on its own or be caused by contact with another surface. Abrasive wear takes place when a rough, hard surface glides across a surface that is relatively softer.

Wear of Metals

Corrosion Wear: Corrosion wear is the gradual deterioration of unprotected metal surfaces, caused by the effects of the atmosphere, acids, gases, alkalies, etc. This type of wear creates pits and perforations and may eventually dissolve metal parts. 30 31. Mechanism: 31 32.

Wear Plates

Steel wear plates may bolt onto a machine that slides or rotates in a manufacturing process, while they can also be found where manufactured parts or minerals are regularly rubbing or abrasively contacting the surface. Wear plate is commonly a type of abrasion resistant steel plate that is considered extremely durable, especially under harsh

What's the Difference Between Types of Wear?

14-1-2016What's the Difference Between Types of Wear? Surface roughness is another important variable for wear. Two-body abrasion is reduced by having smoother surface roughness. This compatibility forms a bond causing parts to seize and even become cold-welded together.
