Description
Technical field
The present invention relates to laser material preparation and forming technique field, particularly relate to a kind of Laser forming repair device
Background technology
The outstanding features such as titanium alloy has that density is low, intensity is high, corrosion-resistant and mechanical behavior under high temperature is good, in advanced opportunity of combat, large-scale
Consumption in the equipment such as aircraft, high thrust-weight ratio aero-engine and industrial heavy gas turbine is increasing.Aircraft, aeroplane engine
Titanium alloy structure part in machine, in addition to bearing service load, bears the heat formed because of engine start-stopping cycle the most simultaneously
Fatigue load, under the common effect of the dual load of alternate stress and heat exhaustion, causes producing in various degree in titanium alloy structure part
Crackle, had a strong impact on the service life of aircraft, aero-engine, even jeopardized flight safety.
Owing to titanium alloy deformation temperature is high, resistance of deformation is big, therefore, it is large complicated that " forging+machining " method manufactures
Aero titanium alloy structural member, not only operation length, complex process, and part machinery processing removal amount is big, manufacturing cost is high,
Production cycle is the longest.Compared with scrapping with by impaired large complicated aero titanium alloy structural member, use and repair and re-manufacturing technology, make
It can be on active service again, for the most cost-effective, reduce the spare parts demand to large complicated aero titanium alloy structural member, carries
Rise aircraft, the ability that quickly re-equips of aero-engine, there is highly important practical significance undoubtedly.
1995-1997, John Ha Pujinsi university of the U.S., Pennsylvania State University, MTS company and Boeing exist
Under U.S. Department of Defense's defense advanced project administration (DARPA) and naval of Ministry of National Defence research office (ONR) joint funding, grind
Send entitled LasformTMTitanium Alloy Aircraft structural member laser fast forming and recovery technique, within 1998, MTS company individual proprietorship is built
Found AeroMet subsidiary, specialize in LasformTMThe through engineering approaches application of technology.LasformTMKnow-why be: with
Titanium alloy hot-rolling stock or forging are substrate, and computer controls laser fusion titanium alloy powder/rapid solidification and successively piles up, and closes at titanium
On gold base, in the way of interpolation, " growth and shaping " goes out the structure such as reinforcement, jointing, therefore, LasformTMTechnical spirit
Upper manufacture is a kind of inside titanium alloy structure part with line and staff control.In Laser Melting Deposition forming process, laser moves
Molten bath extraordinary metallurgy kinetics behavior and non-equilibrium rapid solidification forming core and growth process, decision under ultra high temperature gradient effect thereof
Reinforcement that Laser Melting Deposition shaping " is added " and jointing, its internal grain form, size, crystal orientation, crystalline substance
There is extremely significantly difference between boundary's structure etc. and titanium alloy substrate tissue, and it is inconsistent to directly result in mechanical property between the two, i.e.
Make again through high temperature insostatic pressing (HIP) (HIP), open die forging (Open Die Forging) processing, the Ti6Al4V that AeroMet company manufactures
Titanium alloy structure part, its fatigue mechanics performance is still significantly lower than titanium alloy forging, it is difficult to realize its answering on aircraft structure
With, the most finally in Decembers, 2005 of AeroMet company are forced the closedown that stops doing business.
Northwestern Polytechnical University uses laser solid forming Technique on T i6Al4V and two kinds of titanium alloy forgings of Ti17 to carry out laser forming
Repair, owing to the non-equilibrium rapid solidification structure of laser repairing titanium alloy material and titanium alloy forging matrix forge the difference between annealed structure
Different, and mechanical property is inconsistent between the two, Laser forming repair Ti6Al4V, Ti17 forging, its fatigue behaviour is far below titanium
Alloy forged piece；Beijing Non-Ferrous Metal Research General Academy have studied laser repairing TC11 titanium alloy forging interior tissue and mechanical property thereof,
Result shows, laser repairing TC11 titanium alloy material tissue is dramatically different with forging matrix, and plasticity is significantly lower than titanium alloy
Forging, the overall mechanical property of the TC11 titanium alloy forging of reparation does not reaches aviation military service mechanical property standard.
