| Abstract: | The equation expressing the relationship between the covering rate and the parameters of the laser cladding and the process parameters were derived based on the metallographical measurement. The powder feeding method was used for determining the covering rate in laser coating process. By varying the powder feeding rate v f and scanning speed v s under definite laser power P and beam spot dimensions, the cladding with different thickness was obtained. The factors effected on the covering rate were studied carefully. The results showed that the covering rate becomes larger when the powder feeding rate v f increases or the scanning speed v s decreases. |
