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 astm b689 stress; and Type 3, electroplates containing dispersed submicron particles such h689 silicon carbide, tungsten carbide, and aluminum oxide that are present to astm b689 hardness and wear resistance at specified temperatures.

Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. Typical mechanical properties of nickel electroplated from these baths, and the astm b689 astj of bath operation and solution composition variables on the mechanical properties of the electrodeposit are given in Guide Asgm Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits.
