The influences of duty cycle on the bonding strength of AZ31B magnesium alloy by microarc oxidation treatment

“…Current density has minor effect on film morphology and mainly affects the film compositions [17]. Duty cycle, defined as the ratio of the on time to the whole period (on time + off time) [19], is an important factor in microarc oxidation of magnesium and its alloys. Duty cycle determines the working time in one cycle.…”

Microelectromechanical Systems

“…Nickel-phosphorus and Ni-B alloys can be electrodeposited from slightly acidic nickel electrolytes with the addition of phosphorous acid, H 3 PO 3 , or dimethylamine borane, respectively [55,56]. Nickel-phosphorus alloys form metastable supersaturated solid solutions in the as-deposited state; the grain size decreases with increasing P content, and the alloys become amorphous for P above 9-10 wt %.…”

“…Hardness of amorphous alloys is higher than that of electroplated Ni and may be tuned by gentle annealing; the alloys however are brittle. The yield stress of Ni-P-B alloys with less than 1% each of P or B is higher than 400 MPa and may be increased by pulse plating [56]. An electrolyte used in Ni-P plating is reported in Table 28.…”

Evaluation of electrodeposited ternary Ni-alloys for thermal stability

“…This means that during long operating times, the mechanical properties of the Ni-P electrodeposit can be degraded and thus, the structural integrity of the repaired tubes by this method cannot be assured. To resolve the possible softening of the NiP electrodeposits, an electroplating method for ternary Ni alloys, Ni-P-Fe and Ni-P-B, has been developed by the authors of this paper [8,9]. In addition, an electroplating method of oxide-dispersed Ni composites was tried to endow the structural integrity of the repaired tubes [10].…”
