Introduction of Normal Tungsten Carbide Wear Life Curve Zones-2
The more flat the angle or slope of this line,the longer the predictable wear performance of the WC.In the Zone B phase,the tungsten carbide edge deteriorates at a predicable rate.The rate can be changed by the amount of frictional heat that is being generated by speed or force.The slowing of the work surface speed lower heat generation.The trade off is productivity.The slower the work surface speed the less work that is performed.The frictional heat is breaking down the binder alloy.As the binder is softened more carbide cyrstal grain is exposed and less surrounding support is available so the crystal can fall out of the matrix or be broken.A round or rhombic shape crystal is very much stronger in shape. |
