| Abstract: |
| The transformation of basal body with laser melted clad coating is studied according to the transmission of elastic stress wave which on a laser coating under repeated impact load. First the formation of elastic stress wave which on an equivalent section of laser coating under repeated impact load is analyzed. Next, the coefficients of reverberation & transmission and sound resistance ratio of elastic stress are calculated. The results show that the traveling periodic rule of the elastic wave stress under repeated impact load from laser melted clad coating to basal body is: compressing wave→stretching wave→compressing wave→stretching wave. |
