Adhesive bonding is to use stick receive an agent to make a spare parts gooey the link that be together and forms, also be a kind of not detachable connection. Adhesive bonding has following advantages: ① can will different metal or metal and metalloid stick receive ② together to be able to be stuck receive a few abnormity that solder not easily, complex, tiny stick with ③ of paper-thin spare parts receive contact to be in stress to distributing evener, stick receive sub to have alleviation impact, the action of pare vibration, make contact is in fatigue intensity to be able to raise ④ to stick it is good to receive sub sealing, stick receive an agent to be able to separate two kinds of different metals, can prevent electrochemistry to corrode ⑤ to stick receive weight light, outside light is whole. The defect of adhesive bonding is: Agent of ① adhesive bonding compares sensitive ② to be able to bear or endure to temperature change ageing, acid-proof, alkaline wait for function poorer ③ sticks the examination that receives contact, especially it is difficult that nondestructive examines. Graph 1 practice makes clear, contact is stuck seam of place fight the ability that cut and fights drawing strong, and fight come off with what fight avulse ability loses. Accordingly, stick in the design when receiving contact, should make stick as far as possible seam bear cut or drawing load (graph 1a, B) , avoid to make its bear avulse or the load that come off (graph 15. 40c, D) , still should avoid to make contact bears curve load. Graph 2 it is to stick the example that receives a part. Graph 2 stick the breed that receive a dose various, stick in what mechanical production middling uses receive an agent to have: Organic adhesive, like epoxy resin, get together ammoniac fat, phenolic aldehyde - ethylene; Inorganic adhesive, wait like water glass, its bases is phosphate, silicate.
