Although there is still carbon in carbide form, the amount of carbide is reduced. Knowing the location and distribution of pos- sible carbide formation, the component can be designed to significantly reduce the possibility of carbide formation. Figure 6 shows the same ring with a 0.5 x 0.5 mm chamfer. The chamfer reduc- es carbon build-up at the corner and significantly reduces the risk of carbide formation. Figure 7 shows the three carbon variables at the surface for the 0.5 mm chamfer model. While there is still car- bon locked up in carbide formon the surface of the ring, the amount is small andwill likely be removed by the final grinding operation. ~HTPro For more information: Justin Sims, DANTE Solutions Inc., 7261 Engle Rd.
