Preliminary results ablation of the laser cleaning was introduced in the article elements of the turbine engine of airplane (blades, guide rings, the chambers of oxidising). Cleaning of these units was realized to obtainment of the metallically fine superficial layer for the chosen melts of Fe - C and on the datum feature Nor, prepare to the processes welds or the spraying thermal of coating barriers thermal TBCS. The chosen results of the selection of parameters were introduced in the support about steorology and the cleanness of the superficial layer. Various parameters: laser radiation power density, impulse duration, the frequency control and the laser spot lap stage were applied in laboratory experiments. Laser radiation influence effects were estimated on the surface photo, microstructure, chemical composition in microzones investigation basis. The stereoscopic microscopy, electron scanning microscopy (SEM) and the X-ray analysis were used in investigations. Very good cleaning effects are from oxides, accumulations of turbine blades. In particular, studied elements of aircraft turbine engine, characteristic surface and area topography of heat resistant nickel alloy, tests results of chemical constitution in the characteristic micro-zones of surface layer of high-temperature creep are presented in the paper.
