The degree of defectiveness of assys and parts determines the cost and time of refurbish, meanwhile, a proper examination of the found defects allows to select the suitable technology of the refurbishing of the assy/part. One of our company's services is the participation of our experts in defect finding processes as in the role of the Customer's representative.

DEFECTS FIDNING FOR HOT GAS PATH PARTS AND ASSYS
Prior to gas turbine engine overhaul, all assys and parts, which are subject to micrometric measurements for further calculations of clearances, alightings, etc., are listed within the refurbishment plan document

TECHNOLOGY OF CLEANING OF GAS TURBINE ENGINE HOT PATH ASSYS AND PARTS
ABRASIVE TREATMENT
CHEMICAL STRIPPING
is processed in order to remove the formations, oxides, layers of previous coatings of parts/assys
THERMAL TREATMENT
is processed in order to control the remaining traces of old coatings (otherwise, if these are present, chipping will occur under the influence of high temperature)
When gas turbine hot section assys and parts are refurbished, special attention is paid to the surface preparation for the application of thermal barrier coatings. Properly prepared surfaces ensure high-quality adhesion between the blade alloy and the coating materials (particles).
THERMAL CLEANING
is processed in order to remove the oxides (thermal corrosion) off microcracks
is processed in order to remove the deposits, oxides, layers of previous coatings of cavities and holes of cooling system inner passages
