Effect of Sputtering Current on Growth and Microstructure for Titanium Alloy Coatings onto SiC

摘要：

　　The influences of sputtering current on deposition rate,composition,microstructure evolution and growth mechanism for titanium alloy coatings onto SiC fibers are explored by surface profiler,auger electron spectrometer,X-ray diffraction,scanning electron microscopy and atomic force microscope.The experimental results show that crystallization take place in all coatings with hexagonal structure (α-Ti).As sputtering current is increased,deposition rate and Al content increase,and Ti content decreases.Coating growth mode alsotransforms from V-shaped column grains to equiaxed grains as sputtering current increased.The column grains are generally not single grains,and more nano-grains are composed
