The surface will not chip, flake, crack, peel, or separate from the base metal on the standard ASTM bend tests or under conditions astm b177 extreme heat or cold. The result is a lasting bond and a continuous, smooth, hard surface.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The Armoloy process involves a special pre-cleaning and removing of the matrix astm b177 the base metal’s surface through special proprietary means followed by astm b177 modified electro coating process that causes the chromium element of the Armoloy solution to permeate the surface porosity of the base metal.
Combining values from the two systems may result in non-conformance with astm b177 standard. The values stated in each system may not be exact equivalents; therefore, each system shall be astm b177 independently of the other. For a specific hazards statement, see 3. Coating adhesion and embrittlement shall be tested. Engineering chromium may astm b177 plated directly to the surface of a commonly used engineering metals such as aluminum, nickel alloys, cast iron, steels, copper, copper alloys, and titanium.
There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes. No other units of measurement are included in this standard. Armoloy deposits a crack-free satin matt finish of For methods of chromium electroplating directly on steel see Guide B The Armoloy coating astm b177 becomes integrated with the metal itself. Astm b177 abstract is a brief summary of the referenced standard.
Astm b177 the cleaning and electroplating cycle, high-carbon steel differs from astm b177 steel in regard to its greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit. Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many applications, including food processing and medical environments. For the purpose of this guide, steels containing b1777.
Historical Version s astm b177 view previous versions of standard. Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface oxidation characteristics, and quality. This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of astm b177 standard.
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. 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 during this process that the absolute adhesive characteristics and qualities of the Armoloy are generated. This guide is not intended as astm b177 standardized procedure, but as astm b177 guide for obtaining smooth, adherent coatings of a astm b177 thickness while retaining the required physical and mechanical properties of the base metals.
Nonmagnetic Coatings on Magnetic Basis Metals. This guide outlines the standard procedure for establishing astm b177 maintaining a preparatory cycle for electroplating on high astk steel sstm minimal hydrogen embrittlement and maximal adhesion of the electrodeposited metal. The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. 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.
Electroplating astm b177 plain high-carbon steel introduced problems not found in similar operations on low-carbon astm b177.
Standard – Standard Guide for Engineering Chromium Electroplating ASTM B –
Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, hydrochloric acid treatment, treatment for smut removal, anodic acid etching, and electropolishing shall be performed. Process The Armoloy – Thin Dense Chrome Process Armoloy is a low-temperature, astm b177 process of electro-coating using chrome-plating technology. The solution and application process are carefully monitored to produce a very thin, astm b177 chromium coating.
It is the responsibility of the user of this standard to establish appropriate safety and health practices astm b177 determine the applicability of regulatory astm b177 prior to use. Historical Version s – view previous versions of standard.
Instead of using conventional chrome-plating solutions and parameters, the Armoloy process utilizes a proprietary chemical solution. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.
Standard: ASTM B177
The procedure and requirements for the following are detailed: This guide provides information on the deposition of engineering chromium by electroplating. It is the astm b177 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Copper and Copper Alloys. The preparation of low-carbon steel for electroplating is covered in Practice Astm b177 Link to Active This link will always route to astm b177 current Active version of the standard. Specified chromium electrodeposits on ferrous surfaces are defined in Specification B Armoloy can be applied to all ferrous and nonferrous metals, but is not recommended for titanium or magnesium.
