The bond-dilution effects on the phase diagram of a spin-1 king ferromagnet in a transverse field with random longitudinal field is investigated within an expansion technique for cluster identities of spin- localized spin systems. Longitudinal and transverse magnetizations are studied for several values of thc bond concentration. The critical temperature dependence on the bond concentration, the longitudinal field, and the transverse field are presented. General formulae applicable to structurcs with arbitrary coordination number N are given.
