配制方法：	Although formula 1 is the best-known of the three, it does not give consistently uniform deposits of pit-free iron. For plating on beryllium, formula 3 is recommended, and either 2 or 3 may be used on zirconium. The addition of the wetting agent in formula 3 results in a weaker diffusion bond.
