Surface Wear

Wear Reduction

More Details on Surface Property enhancement is to be found in the links below the table

Wear is defined as surface damage involving a progressive loss of material, due to relative motion between it and a contacting surface or substance.   All contacting surfaces with relative movement are subject to wear.   Normally the method of eliminating and reducing surface wear is to provide a film of lubricant between the surfaces.   However the condition of the surface and especially its hardness has can be controlled to mitigate the negative effects of surface interactions. A hard material is more resistant to wear and abrasion compared to a soft material. Methods of providing a surface with desirable properties include:

• Selecting a suitable parent material
• Carburising (Case Hardening)
• Nitriding
• Coating Surface
• Attaching an intermediate thin strip of suitable material
