The surface roughness of the laser shock peened medium has effect on the high frequency of laser-generated surface acoustic waves. As the impact times of the laser shock peening increase, the surface roughness has little effect on the dispersion of laser-generated surface acoustic waves. From the theoretical curve and experiment curve, it can ...

A parametric surface was reconstructed at a local area of each sample point, and a believing neighbor area was generated based on a given error. A new parametric surface was recomputed, and a larger believing area was generated. The surfel with largest believing area was reconstructed, and the original model was approximated by the surfel in an as large as possible local area.

The results show that α-Al2O3 in the two kind s of coatings decreases while the γ-Al2O3 increases after spraying. Rutile-TiO2 transforms to brookite-TiO2 and the inners tress of coating was increased so as to aggravate the expansion of cracking. The pores are small but dense in the conventional coating while bigger but loose in the nano-structured coating. The pores in the nano-structured coating exist almost inside the partially melted region. The pores generated during spraying and the cracks generated during the course of thermal oxidization because of thermal stress are the direct reasons why coatings fail.
