...Abstract Abstract A femoral knee implant was returned to the casting vendor for analysis after exhibiting poor bond strength between the cast substrate and a sintered porous coating. Both the coating and the substrate were manufactured from a cobalt-chromium-molybdenum alloy. Metallographic...

... of the constituents: the smaller the grains, the faster they dissolve. In refractories, however, the smallest grains, by design, bond with the coarser grains (the aggregate), and since this bonding occurs by liquid-solid sintering, the matrix materials (the bonding phases) have the lowest melting temperatures...

... susceptible to failure. Also, the sintering temperature is high enough to result in a β transformation of the microstructure. This microstructure decreases the fatigue-initiatior. resistance of the material and can degrade the high-cycle fatigue performance of the component. Alternate bonding techniques...

... required FTIR analysis. By determining the nature of the layer via FTIR, the source for failure was indicated as both material and process related. In other words, the resistor termination design, because it incorporated polymeric materials and thus limited metallurgical bonding, was not appropriate...

The wear rate for the reaction-bonded type was higher, the wear mode being by “grain pullout.” The other two types had...
