and NiFe2O4 ceramic powder and Cu-Ag powder as fillers. Strength of bonded joint, microstructure of bonding interface and phase composition of the adhesive layers were characterized. The effects of binders... of binders behavior at 800 ℃ is responsible for the decrease in strength of bonded joint. Volatile of decomposition products and phase reaction also cause porous adhesive layer which weakens the strength......

occurs[1-7]. It has been shown that the adhesive effectively improves the strength of cracked portions of the concrete and increases its ability to deflect in a ductile manner under loading. However... is similar to the previous re-loading. This indicates that the strength of cracked section is repaired and improved by the release of adhesive from the broken-open fibers into the crack, and the cracking......

, and Ar gas acts as the protection gas with flow rate of 15 L/min. The average shear strength of the welding sample with adhesive layer addition reaches 41.33 MPa. Compared with that without adhesive layer addition, the average shear strength of weld joint increases by 1.44 times. The increases of weld penetration and width by adding adhesive layer promote the combination of the steel ......

on ZK60 and ME20 alloys was investigated. The results indicated that differences in the alloy compositions significantly influenced the initial deposition process and the adhesive strength, corrosion... activation rather than on the precipitates. Owing to differences in the initial deposition process, the coating on ZK60 alloy had higher adhesive strength and better corrosion resistance than that on ME20......
