بررسی تجربی فرایند پوشش دهی با لیزر پودر اینکونل ۷۱۸ بر روی فولاد ۱۳H

In the present research, the coating process of Inconel ۷۱۸ powder on the H۱۳ steel substrate by direct powder deposition method with the help of ۱ KW continuous fiber laser has been investigated. Hence, the effects of process parameters such as laser power, powder feed rate and laser scanning speed on the geometrical characterstics of the clad such as height and width of the clad are examined. In order to perform a comprehensive investigation on the effect of input parameters and their interactions on the height and width of the clad, design of experiment method based on response surface methodology is employed. The results show that the laser scanning speed and powder feed rate are as the important factors affecting the clad height, so that the clad height increases with increasing powder feed rate and decreasing laser scanning rate. Also, it is proved that by increasing the laser power and decreasing the laser scanning speed the width of the clad is increased.
