NOTE 6—When the thickness of the nickel underplate has a detrimental impact on the mechanical properties or bondability of the substrate, the nickel thickness may be reduced to a non-detrimental level as speci? Therefore, if all the articles in a production lot are to meet the thickness requirement, the average coating thickness for the production lot as a whole will be greater than the average necessary to ensure that any single article meets the requirement see 8.
If they do not, Test Method B identi? A minimum rinse time of 2.
ASTM B – 18 Standard Specification for Electrodeposited Coatings of Gold for Engineering Uses
To prepare equilibrated water,? They must be smooth and as free of scratches, gouges, nicks, and similar imperfections as possible. All other metals are considered impurities and shall not be present in amounts greater than 0. Oxidation of co-deposited metals can make soldering more difficult.
Gold-plated parts exhibit excellent wear resistance, high hardness, corrosion resistance, high conductivity, solder-ability and excellent performance at high temperatures. It is customary that allowance for plated coatings be included within the part tolerance. It is soluble in water and forms carbonic acid that ionizes and is at equilibrium at 0. Type, Code, and thickness or mass per unit area see Section 4. Thus, the appearance of test coupons may serve as an indication of an approaching need for the activated carbon treatment.

Test Method B contains several plans and also gives instructions for calculating plans to meet special needs. The conductivity of the water extract is measured, and the increase in conductivity due to g488 salts and other conducting impurities is calculated.
When Guide B is speci? Can be the source of corrosion products or tarnish? Iron, nickel and cobalt combined shall be less than 0. The cross-sectioning and magnetic methods measure the geometrical thickness of the gold present.
Bb488 other metals, excluding potassium and nitrogen, shall be considered impurities and shall not be present in amounts greater than 0. Deposit purity should be determined on samples at plating conditions representative of actual production. Since many gold coatings have a density lower than the theoretical density of gold No separation of the coating from the substrate shall occur.
With over 50 years of combined experience, our staff has the knowledge to finish your metal part to your exact specifications and to the tightest tolerances. CO2 is a component of air.
This standard does not purport to address all of the safety concerns, if any, associated with its use. Coatings with purities of It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Hence, most average coating thicknesses will be greater than the speci? Other calibration standards for gold are generally certi? When the work load is erratic, each addition should be based on bath analyses.
When plated parts are used in mating applications, the maximum thickness shall not exceed the tolerance speci? Variation in the coating thickness from point to point on a coated article is an inherent characteristic of electroplating processes.
This standard has been approved for use by agencies of the Department of Defense. Once it has been established that the co-deposited metallic impurity limitations are being continuously met in production, frequency of determination can be reduced.
NOTE 14—The adtm to be selected will depend upon the gold thickness, the nature of the basis metal, the nature and thickness of any intermediate layers or underplate, the shape of the gold-coated part, and its intended service asstm. All our processes are certified to ISO At APP, we are committed to meeting or exceeding your expectations for your gold plating application through efficient, effective processes, high quality control and superior customer service.

However, the use of these undercoatings requires the approval of the purchaser. Gold is the ultimate precious metal for electrical contact plating.
In addition, the average coating thickness on articles will vary from article to article within a production lot. Test Method B contains four sampling plans, three asstm use with tests that are nondestructive and one with those that are destructive. Last previous edition approved in as B — 01 e
