The surface alloying specimen was made from the steel 45 substrate overcoating by oxygen-acetylene flame spraying Fe-Cr-Ni alloy powder and laser *** chemical heterogeneity was clearly observed on the transition zone between the laser melted zone and heat-affected zone by means of EPMA,AES and *** heterogeneity is rather serious during high temperature tempering,so the decarburization on the transition zone side and the recarburization on the melted zone side were found.

Ethylene-Vinyl Acetate （EVA） redispersible powder and latex were used to modify mortar. Three kinds of curing regimes： standard curing, high temperature curing and freeze-thaw circle curing were adopted to cure the bonded samples. Bonding strength of EVA modified mortar was tested at 28 days. The development of bonding strengths under all three curing regimes were discussed and compared. The experimental results show that bonding strength increases with the increase of EVA content in mortar. The curing regime used within 28 days is critical according to the bonding strengths values under three curing regimes for different ages. The reasons of that the EVA can improve the bonding strength were analyzed.
