It also has good creep resistant and oxidation resistance etc. simultaneously, and it is resistance to that this becomes space flight, aviation and automobile engine
The material of the great competitiveness of heat structure part.Therefore, the development of TiA1 alloys is constantly subjected to the concern and again of countries in the world researcher
Depending on.
The room temperature elongation percentage of TiAl-base alloy usually changes between 0.3-4%, and surrender and tensile strength then exist respectively
Between 250-600MPa and 300-700MPa.The early stage TiAl-base alloy of research is mostly as cast condition.Usual as-cast structure is coarse tree
Dendrite, it is easy to loose and component segregation is generated, thus its brittleness is high, room temperature ductility is almost nil.
Although TiAl-base alloy has many advantages, and technically achieves many important breakthroughs, but still there are many performances
The problem of aspect, needs to solve, for example, the low temperature-room type plasticity of TiAl alloy and incident formability it is poor, for 1000 DEG C with
On the high-temperature component that uses there is relatively low elevated temperature strength, 800 DEG C or more of antioxygenic property is insufficient, tensile strength, modeling
Property with fracture/creep resistance there is inverse relationship etc., so using being subject to certain restrictions.
Magnetron sputtering is one kind of physical vapour deposition (PVD) (Physical Vapor Deposition, PVD), general to splash
The method of penetrating can be used for preparing more materials such as metal, semiconductor, insulator, and with equipment is simple, easily controllable, plated film area is big
And the advantages that strong adhesive force, and the magnetron sputtering method that the seventies in last century grows up is even more to realize high speed, low temperature, low damage
Wound.Because being to carry out high-speed sputtering at low pressure, it is necessary to effectively improve the ionization level of gas.Magnetron sputtering passes through in target the moon
Pole surface introduces magnetic field, and plasma density is improved to the constraint of charged particle to increase sputtering raste using magnetic field.
Precinct laser sintering is to make the energy using infrared laser, and the Modeling Material used is mostly dusty material.When processing,
Powder is preheating to the temperature of slightly less than its fusing point first, then paves powder under the action of striking off rod；Laser beam exists
It is selectively sintered according to layering cross section information under computer control, carries out next layer of sintering after the completion of one layer again, all
Remove extra powder after being sintered, then can be obtained by a part sintered.Process materials ripe at present be wax powder and
Molding powder, the technique being sintered with metal powder or ceramic powder is also among research.
Currently, more using the research of magnetron sputtered deposition technology prepares coating, many scholars are using this technology in metal
Matrix surface prepares TiO2、Al2O3Equal ceramic coatings, this technology comparative maturity, but the bond strength of coating and matrix is big
About 70Mpa or so, under harsh severe operating mode, ceramic coating will produce crackle after working long hours, and can seriously take off
Phenomena such as falling, coating duty service life are shorter.
