Explanation:
We just received a large order for plating parts with “low stress nickel.” What is a low-stress deposit? P.N.

A. As you are probably aware, there are different types of nickel plating baths. The workhorse is the Watts nickel plating bath, which consists of nickel sulfate, sulfuric acid, small amounts of chloride ion and water. This particular bath gives a deposit with residual stress, and that residual stress can cause peeling, blistering and tearing of the deposit. In addition, the deposit may be warped or cracked, and adhesion can be reduced dramatically.

The residual stress in the nickel deposit is affected by the plating bath composition. This table shows some stress values for different types of nickel plating baths:

There are two ways that residual stress can be reduced in a plating situation. Stress reducing agents such as saccharin can be added to the bath, or, if the customer specifies a low-stress deposit that is additive-free, a sulfamate-based plating solution is called for. The sulfamate plating bath is more expensive than the Watts-type bath.

The substrate itself also can influence the residual stress of the deposit, as can the temperature of the bath. For example, the stress from a nickel sulfamate plating bath at a temperature of 65°F is 13,200 psi, but 2,500 psi at 104°F.
