ASTM B() Standard Specification for Autocatalytic (Electroless) Nickel-Phosphorus Coatings on Metal Scope This . This ASTM B standard specification covers the requirements for electroless nickel-phosphorous coatings on metal. For more details call us. The procedure in our factory is carried out according to: AMS-C, or ASTM B The thickness of the coating and the treatments is displayed in the tables.

NOTE 14—To protect the edges, electroplate the specimens with a minimum of 5? Additional requirements for internal stress, purity, and elongation may be necessary for some applications. Users of this standard are expressly advised that determination of the validity of any such patent b7333-04, and the risk of ast, of such rights, are entirely their own responsibility.
For example, coating with a test result for phosphorus of 9. An example is leaded steel which may exhibit liquid or solid embrittlement after heat treatment.

The tests for these quali? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Santa Clara Plating Co.
When required, one of the following tests can be used on the plated part or specimen. Consideration of the risk of stripping the deposit should always be considered when selecting this coating. NOTE 13—Eddy-current type instruments give erratic measurements due to variations in conductivity of the coatings with changes in phosphorus content.
Care should be taken to control the humidity between tests. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Any such defects on signi? It is characterized by industrial atmosphere exposure on steel substrates in dry or oiled environments. Continue to boil the water for 30 min. The thickness of the coating and the treatments is displayed in the tables below: The weight percent of phosphorus shall be in the range designated by type classi?
Coatings with phosphorus contents greater than Electroless Nickel Please note that price shown is for minimum thickness. This standard is not included in any packages. This standard does not purport to address all of the safety concerns, if any, associated with its use. Service Condition 0 0.
Electroless Nickel Plating
Base metal condition, undercoats, surface preparation, and post processing all have a signi? For coatings requiring alloy analysis and corrosion testing weekly sampling should be considered as an option.
After rinsing and air drying, examine the part for blue spots, which form at pore sites. Please note that price shown is for minimum thickness. In the case of dissatisfaction occurs with the results of a test, the producer may make a claim for a hearing. The amount of material removed varies from nothing to 0. The inspection lot is then classi?
Typical environments include light-load lubricated wear, indoor corrosion protection to prevent rusting, and for soldering and mild abrasive wear. After 3 min contact, rinse, and apply a solution of alizarin sulfonate prepared by dissolving 1.
Electroless Nickel Coating
This standard has been approved for use by agencies of the Department of Defense. The test is performed by rotating a plated panel under rotating rubber wheels and weighing the panel after each cycles for weight loss. Please first log in with a verified email before subscribing to alerts. bb733-04
NOTE 11—The autocatalytic nickel process is dynamic and a daily sampling is recommended. Subscription pricing is determined by: The n733-04 of a statistical regimen to establish the control limits and frequency of analysis may be employed to ensure quality deposits are produced. The following analysis wavelength lines have been used with minimum interference to determine the alloy.
Undercoats may be required to facilitate rework.

The wear rate shall be speci? They are also used for the salvage of worn or mismachined parts.
Its main use is in engineering applications.
