Along with the development of hard-core technologies such as advancing by leaps and bounds of modern science and technology, particularly space flight, aviation, nuclear power, more and more higher requirement has been proposed for the performance of material.At present, no matter be from economy or from the angle of practicality, single-material has been difficult to satisfy the demand of modern production technology to the material over-all properties, and therefore, the Materials science worker just is being devoted to research and develop the interconnection technique of novel material and foreign material both at home and abroad.Titanium aluminium base alloy has that density is little (to be about 3.8g/cm
3), advantage such as specific tenacity height, good rigidly, good high-temperature mechanical property and oxidation-resistance, be considered to a kind of ideal, be rich in Aeronautics and Astronautics, military affairs and the civilian new type high temperature structured material of development prospect.TiB
2Being connected to use in sintering metal and TiAl alloy of hot environment to(for) the TiAl alloy has very important significance.Because physics, the chemical property of these two kinds of materials differ greatly, and fusing point is than higher, and traditional fusion welding method is difficult to realize the connection of these two kinds of materials, and possible method of attachment relates generally to diffusion and connects and soldering.But TiAl alloy and TiB
2Fragility is mutually more in the ceramic-metallic diffusion jointing reaction product, and joint efficiency is very low, and unrelieved stress is very big at the interface, and joint quality is difficult to control, therefore is difficult to be applied.Although the effect of relieve stresses has been played in the fusing of solder in the brazing process; but brazed joint use at high temperature is restricted; and diffusion connects and soldering is very high to the requirement of equipment, the heating installation that general requirement is bigger and generally need vacuum or protective atmosphere.Publication number provides a kind of " pottery causes the self-propagating combustion connection method with metal field " for the patent of CN1475463A, the defective that this method exists is need with special ignition device to connect, the required equipment relative complex, and require the necessary nickel plating of ceramic surface, technology is more loaded down with trivial details.
Summary of the invention
The object of the present invention is to provide a kind of TiAl alloy and TiB
2Ceramic-metallic self-propagating reaction method of attachment should method is simple, overcome prior art equipment complexity, defective that technology is loaded down with trivial details.Present method comprises the steps: one, gives TiAl alloy and TiB with the higher frequency electromagnetic field

2Sintering metal applies the axle pressure of 30-60MPa, is clipped in TiAl alloy and TiB
2Powder compact between the sintering metal is realized TiAl alloy and TiB by the higher frequency electromagnetic field concurrent straggle reaction of being conigenous that ignites
2Ceramic-metallic connection, described powder compact by the powder mixes of Ti, Al, C, Ni and Mo evenly the back compacting form or by the powder mixes of Ti, Al, B, Ni and Mo evenly the back compacting form.The weight percent of being suppressed each component of powder compact that forms by Ti, Al, C, Ni and Mo is: Ti:27.5~45%, Al:15~25%, C:8~10%, Mo:3~5%, surplus are Ni; The weight percent of being suppressed each component of powder compact that forms by Ti, Al, B, Ni and Mo is: Ti:22.5~40%, Al:15~20%, B:10~15%, Mo:4~8%, surplus are Ni.The weight percent of being suppressed each component of powder compact that forms by Ti, Al, C, Ni and Mo is: Ti:27.5~45%, Al:15~25%, C:8~10%, Mo:3~5%, surplus are Ni; The weight percent of being suppressed each component of powder compact that forms by Ti, Al, B, Ni and Mo is: Ti:22.5~40%, Al:15~20%, B:10~15%, Mo:4~8%, surplus are Ni.
After adopting high-frequency induction heating that special composition Ti-Al-C-Ni-Mo or Ti-Al-B-Ni-Mo middle layer powder pressed compact are ignited among the present invention, utilize the self-propagating reaction liberated heat as connecting thermal source, simultaneously auxiliary TiAl alloy and the TiB of realizing down in the higher frequency electromagnetic field
2Sintering metal connects, and powder compact of the present invention is very big as its exothermic heat of reaction amount of middle layer reaction system, the temperature of igniting very low and also ignite after can realize self-propagating reaction.Mainly in order to reduce the ignition temperature of system, Ti-C or Ti-B are main heat release system in the adding of Al in the powder pressed compact of middle layer, and the adding of Mo can improve the wettability between Ni and the TiC.Ni in the powder pressed compact of middle layer can improve at the interface wetting situation and density on the one hand mainly as the thinner of entire reaction, can improve the mechanical behavior under high temperature and the use temperature of joint on the other hand.The radio-frequency induction coil that generates an electromagnetic field is both as giving TiAl alloy and TiB
2The device of sintering metal preheating has reduced the complexity of equipment again as the ignition device of self-propagating reaction; Do not need in the connection procedure to carry out Nickel Plating Treatment to any position.Present method has simple, the efficient and energy-saving advantages of step, has bigger promotional value.
