Standard: ASTM B177

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The result is a lasting astm b177 and a continuous, smooth, hard surface. The preparation of low-carbon steel for electroplating is covered in Practice B Link to Active This link will always route to the current Active version of the standard. Astm b177 chromium electrodeposits on ferrous surfaces are defined in Specification B Armoloy makes astm b177 possible to use standard ferrous steels in place of astm b177 steel in many applications, including food processing and medical environments.

Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface oxidation characteristics, and quality. For methods of chromium electroplating directly on steel see Guide B This guide is not intended as a standardized procedure, but as a guide for obtaining smooth, adherent coatings of a desired thickness while retaining the required physical and mechanical properties of the base metals.

Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, astm b177 anodic cleaning, hydrochloric acid treatment, treatment for smut removal, anodic acid etching, and electropolishing shall be performed. Combining values from the two systems may result in non-conformance with the standard.

For the purpose of this guide, steels containing 0. ASTM does not give any warranty express or implied or astm b177 any representation that the astm b177 of this abstract are accurate, complete or up to date. The Armoloy coating actually becomes integrated with the metal itself.

No other units of measurement astm b177 included in this standard. For a specific hazards statement, see 3. It is the responsibility of the user of this astm b177 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. During the cleaning and electroplating cycle, high-carbon steel differs from low-carbon steel in regard to its greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit.

Bearing Astm b177, etc.

There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes. The Armoloy process involves a astm b177 pre-cleaning and removing of the matrix on the base metal’s surface through special proprietary means followed by a modified electro coating process that causes the chromium element of the Armoloy solution to permeate the surface porosity of the base metal.

The surface will not chip, flake, crack, astm b177, or separate from the base metal on the standard ASTM bend tests or under conditions of astm b177 heat or cold. 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.

It is the responsibility of the user of this standard to establish astm b177 safety and health practices and determine the applicability of regulatory limitations prior to astm b177.

Historical Version s – view previous versions of standard. The solution and application process are carefully monitored to produce a very thin, dense chromium coating.

This abstract is a brief summary of the referenced standard. Copper and Copper Alloys. Astm b177 abstract is a brief summary of the referenced standard. This is sometimes called “functional” or “hard” chromium and is usually applied directly to the basis metal astm b177 is usually thicker than decorative deposits. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.

Engineering chromium may be plated directly to the surface of a commonly used engineering astm b177 such as aluminum, nickel alloys, cast iron, steels, copper, copper alloys, and titanium. Link to Active This link will always route to the current Active version of the standard. Process The Armoloy – Thin Astm b177 Chrome Process Armoloy is a low-temperature, multi-state process of electro-coating using chrome-plating technology. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This guide outlines the standard procedure for establishing and maintaining a preparatory cycle for electroplating on high carbon steel producing minimal hydrogen embrittlement and maximal adhesion of the electrodeposited metal. 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.

The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. Nonmagnetic Coatings astm b177 Magnetic Basis Metals.
