Description
Technical field
The present invention relates to a kind of alloy powder material being suitable for laser melting coating, particularly relate to a kind of for internal combustion engine whirlpool
The Co-based alloy powder that wheel supercharger wheel disc is repaired, belongs to C23C24/10 (2006.01) the I skill in IPC International Patent Classification (IPC)
Art field.
Background technology
Turbocharger be a kind of in hot environment ultrahigh speed rotate machinery, its parts turbine disk working speed up to
10000～20000 revs/min, the machinery of such high speed rotating often causes damage because installing and using improper, makes user suffer
Certain economic loss.May cause because of vibration when high speed rotating owing to there is gap when the blade on the turbine disk assembles
Accident, so for fixing blade, often after blade assembles, on the falcon tooth of both sides, riveter point is to fasten blade, but riveting point usually can
Cause stress to concentrate when high speed rotating, thus cause wheel disc to lose efficacy, there is crackle and accidents caused in tenon tooth.Therefore, it is necessary to adopt
Take certain mode to carry out riveting point restoring maintenance.
The Electric Welding Buttering Technique mode used at present, all can inevitably produce big thermal deformation, height this for the turbine disk
Precise part all can not bear.
Therefore, suitable turbocharger wheel disc restorative procedure is selected, it is ensured that adding of the turbocharger wheel disc after reparation
Work error is little, thermal deformation is little, standardization is strong, repair after wheel disc performance good, be problem the most urgently to be resolved hurrily.
Laser melting coating recovery technique, as the re-manufacturing technology of a kind of advanced person, has obtained rapid popularization in recent years and extensively should
With.
At present, corrosion-inhibiting coating both domestic and external uses the traditional handicrafts such as spraying, surfacing to prepare, and these traditional handicrafts prepare
Corrosion-inhibiting coating has some to be difficult to the problem overcome.Such as: anticorrosive coat actual functional capability layer is the thinnest；Manufacture in coating procedure and be easily generated gas
Hole, the defect such as it is mingled with；Coating and mother metal faying face are non-metallurgical binding, and problems such as coming off easily occurs in coating.And use laser to melt
Coating technique manufactures corrosion-inhibiting coating then can effectively solve problem above, and the process conditions greatly reducing manufacture corrosion-inhibiting coating are wanted
Ask, reduce cost simultaneously.
Laser melting coating is as the re-manufacturing technology of a kind of advanced person, along with improving constantly of laser power and stability,
Rapid popularization and extensively application are arrived.Laser melting coating is to obtain in metal surface to be combined with matrix strong metallurgical, and pore-free, splits
The advanced re-manufacturing technology of the high performance surface coating of the defects such as stricture of vagina, it can be by dystectic alloy material cladding in low melting point
Substrate surface, it is also possible on low-cost substrates, prepare high performance face coat, with replace the most senior, high performance
Integral material, saves precious metal, reduces parts cost.Laser melting coating solves many conventional methods and is difficult to processing or cannot
The problem of processing, provides a kind of technology effective method unique, advanced for product remanufacturing.
But, the alloy powder that laser melting coating is special in the market is actually rare, and the traditional handicraft such as surfacing, spraying institute
The alloy powder used, is to be allocated by different proportion, and various Ni-based, the cobalt needed for the form preparation of powder mixing machine
Base, iron(-)base powder.These hybrid alloys powder exist such as mix uneven, granularity difference is big, fusing point is different, composition
Deviation, the coefficient of expansion not parity problem, causes in actual cladding uncontrollable crackle, pore, segregation, performance is unstable, be difficult to
The defects such as machine adds.
People alloy powder material side needed for research and utilization laser melting and coating technique carries out part of appliance reparation in recent years
Face has made some progress, such as.
