Abstract
The machinability of two classes of high-temperature composites (SiC whisker/2124 aluminium and SiC whisker/Al2O3) with an abrasive waterjet (AWJ) was investigated. The as-machined surfaces of the composites were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and profilometry to determine the surface finish. Microhardness measurements were also performed on the as-machined metal matrix composites. AWJ appears to be a quite promising machining method due to its fast speed and economical operation. It gives relatively smooth surfaces coupled with minimum subsurface microstructural damage.
