Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. Coatings shall be sampled, tested, and conform accordingly to specified requirements as to appearance, thickness measured either destructively by microscopical or coulometric method, or nondestructively by magnetic or X-ray methodadhesion examined either by bend, file, heat and quench, or push testporosity assessed either by hot water, zstm, or flowers of sulfur testworkmanship, and hydrogen embrittlement relief.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine g689 applicability of regulatory limitations prior to use. When electroplated nickel is required to have higher hardnesses, greater wear resistance, certain residual stress values and certain leveling characteristics, sulfur and other substances are incorporated in the nickel deposit through the use of certain addition agents in the electroplating solution.

When electroplated nickel is required to have higher hardnesses, greater wear resistance, certain residual stress values and certain leveling characteristics, sulfur and other substances aztm incorporated in atm nickel deposit through the use of certain addition agents in the electroplating solution.

This standard is not included in any packages. We have no amendments or corrections for this standard. Metal parts shall undergo pre- and post-coating treatments to reduce the risk of hydrogen embrittlement, and peening. Typical mechanical properties of nickel electroplated from these baths, and the combined effect of bath operation and solution composition variables on the mechanical properties of the electrodeposit are given in Guide B As the voice of the U.

Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. Type 1, coatings electroplated from solutions not containing hardeners, brighteners, or stress control additives; Type 2, electrodeposits used at moderate temperatures, and contain sulfur or other codeposited elements or compounds that are present to increase the hardness, refine grain structure, or control internal stress; and Type 3, electroplates containing dispersed submicron particles such as silicon carbide, tungsten carbide, and aluminum oxide that are present to increase hardness and wear resistance at specified temperatures.
