Abstract
Repair of blades from the MAR-M200 alloy is of great interest, since this procedure is much more profitable than manufacturing new products. At the same time, there are great difficulties associated with the fact that this alloy does not tolerate the high temperature [1], the high speed cooling and thermal cycling [3,4] that accompany the laser surfacing process. In this regard, an important study will examine the deposition regimes with pauses between the passages, designed to reduce the cooling speed and, as a consequence, the temperature drop. The article presents the results of the influence of the duration of a pause between passages on the structure and properties of samples obtained by laser cladding. Four variants of pause-0, 25, 50 and 100 seconds were investigated.
