Thin film nickel‐phosphorus alloys are electrodeposited at a high rate using a specialized rapid electrolyte flow system. Current densities up to 2.33 A/cm2, which are difficult to maintain in conventional plating processes, can be used to produce satisfactory films. The deposits are characterized by x‐ray diffraction and differential scanning calorimetry. Phosphorus content decreases with increasing current density and is virtually independent of the electrolyte flow rate above 5.7 m/s, where the system is operating in the turbulent regime. Deposit structure depends strongly on the phosphorus content; it is amorphous or highly microcrystalline at >14 atom percent (a/o) and crystalline at
