Abstract

The effects of the direct implantation of cations into the lattice of alumina, silicon carbide, and titanium diboride have been studied. Alumina implanted with chromium, titanium, and zirconium ions remains crystalline and shows an increase in hardness and fracture toughness. Titanium diboride experiences similar trends. In contrast, silicon carbide becomes amorphous when implanted with chromium ions, becomes less hard, but shows an increased fracture toughness. The response to scratching and annealing is also discussed.
