title = "OBSERVED CHANGES IN FRACTURE STRENGTH FOLLOWING LASER IRRADIATION AND ION BEAM MIXING OF Ni OVERLAYERS ON SINTERED ALPHA-SiC.",
abstract = "Pulsed laser annealing and ion beam mixing are currently being investigated as surface modification techniques in an attempt to enhance the mechanical properties of polycrystalline alpha -SiC. Thin Ni overlayers (20nm-100nm) are evaporated onto the SiC surface. The specimens are subsequently irradiated with pulses of a ruby or excimer (KrF or XeCl) laser or bombarded with high energy Si** plus or Xe** plus ions. Following laser irradiation, the fracture strength of the SiC is increased by as much as approximately equals 50%, but after ion beam mixing, no strength increase is observed. Weibull statistics are used to characterize the SiC fracture strength data before and after surface modification. Cross-sectional transmission electron microscopy (X-TEM), scanning electron microscopy (SEM), secondary ion mass spectroscopy (SIMS) and Rutherford backscattering (RBS) techniques are used to characterize the modified SiC in order to determine the cause for the increase in fracture strength and the extent of mixing as a result of the surface modification.",
