A civil turboshaft engine supporting transmission system pre-research project, to verify the feasibility of laser additive repair method re-drive system typical parts on typical materials, after repair performance to meet the requirements of the tail stock shaft spline, na primjer, in the use of the process of wear, the use of laser melting additive repair technology to repair the parts, and to examine the performance of all aspects.
Project sample
The spline is divided into internal spline and external spline, the material of the internal spline is 15-5ph, the material of the external spline is 9310 steel, there is no restriction on the material used for laser additive repair, it can meet the performance requirements. The metallographic inspection of the laser clad material meets the technical requirements, and there are no defects such as porosity, slagging and cracks.
Effect after laser cladding repair of external spline simulated parts
External spline mock-up after laser cladding repair and fluorescence flaw detection
After the mechanical property test is passed, a simulated sample repair is carried out. To ensure a certain thickness after fusion repair, and the scan path needs to be designed according to the spline shape.
