      Zhao, X.; Yu, T.; Zhao, Y.; Zhang, Y.; Sun, X.; Ma, Z.; Li, M., and Zhang, T., 2018. The investigation of the morphology and failure types of pre-placed CBN on Cu-Ni-Sn-Ti bonded to steel by laser process. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 486–489 . Coconut Creek (Florida), ISSN 0749-0208. Pre-placed CBN on Cu-Ni-Sn-Ti was bonded to AISI 1045 steel with various process parameters by laser in the present paper. The wettability and the oxidization condition of the CBN in laser bead were analyzed by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) respectively. The failure types of the CBN in laser bead were observed by optical microscopy (OM). The results show that the wettability of the CBN and Cu-Ni-Sn-Ti mixed powder is pronounced because of active element Ti regardless the CBN size and laser processing parameters. Oxidization is serious after laser process even...
