2000 Conferences and Exhibition - Challenge the Experts
"Wear Resistant Coatings"
Held on 7th December 2000 at the Ardencote Hotel and Country Club, Lye Green Road, Claverdon, Warwickshire.
As is well understood there are different kinds of wear mechanism - Abrasive, adhesive, fretting and erosion, each requiring surface characteristics most suitable for the particular condition. Where surfaces are sliding against each other (adhesive) the possibility of a breakdown in lubricant for whatever reason may well result in the transfer of the wear to the mating component particularly if the criterion for material selection is based only on surface hardness. On the other hand wear by abrasive grains may be catered for without consideration.
Erosion may be prevented by using hard materials having a low coefficient of friction whilst fretting is often dealt with by hard on hard surfaces such as Tungsten Carbide against Tunsten Carbide. There are many different materials available to provide resistance to these differing conditions and when other factors such as shock loading or corrosion are superimposed on types of wear, coating selection becomes more difficult than simply using the hardest material available.
The meeting is designed to enable engineers to make the right material selection and also highlight the different surfacing technologies most suitable for the operating conditions. Surface coatings techniques by materialdeposition such as thermal spraying, physical vapour deposotion (PVD) and weld surfacing will be discussed. Also special treatments which change the existing surface characteristics without external application of unrelated materials.
