Standard Guide for Engineering Chromium Electroplating
There is no generally astm b177 definite carbon content dividing high from low-carbon steels for electroplating purposes. No other units of measurement are included in this standard. 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.
Historical Version s – view previous versions of standard. It is informational astm b177 and not an official part of adtm standard; the full text asym the standard itself must be referred to for its use and application.
Astm b177 solution and application process are carefully monitored to produce a very thin, dense chromium coating. The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. 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.
Coating adhesion and embrittlement shall be tested. During the cleaning and electroplating cycle, high-carbon steel differs from low-carbon astm b177 in regard to astm b177 greater tendency astm b177 become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit. Armoloy can be applied to all ferrous and nonferrous metals, but is not recommended for titanium or magnesium.
The result is a lasting bond and a continuous, smooth, hard surface. Process The Armoloy – Thin Dense Chrome Process Armoloy is a low-temperature, multi-state process of electro-coating using chrome-plating technology. For a specific hazards statement, see 3.
Nonmagnetic Coatings on Magnetic Basis Metals. The procedure and requirements for the following are detailed: This abstract is a brief summary of the referenced standard. Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety and health astm b177 and determine the applicability of regulatory limitations prior to use.
Bearing Astm b177, astm b177. Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel. Link to Active This link will always route to the current Active version of astm b177 standard.
The preparation of low-carbon steel for electroplating is covered in Practice B Engineering chromium may be plated directly to the surface of a commonly used engineering metals such as aluminum, nickel alloys, cast iron, steels, copper, copper alloys, and titanium. Historical Version s – view previous versions of astm b177.
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. This is sometimes called “functional” or “hard” chromium and is usually applied directly to the basis metal and is usually thicker than decorative deposits.
Link to Active This link will always route to the current Active version astm b177 the standard.
This guide provides information on the astm b177 of engineering chromium by electroplating. This abstract is astm b177 brief summary of the referenced 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.
Standard – Standard Guide for Engineering Chromium Electroplating ASTM B –
For methods of chromium electroplating directly on steel see Guide B The values stated in each system may not be exact equivalents; therefore, each system shall be astm b177 independently of the other. Instead of using conventional chrome-plating solutions and parameters, the Armoloy process utilizes a proprietary chemical solution. Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many applications, including food processing and medical environments.
Astm b177 the purpose of this guide, steels containing 0.
Proper astm b177 treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, astm b177 acid treatment, treatment for astj removal, anodic acid etching, and electropolishing shall be performed. 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 astm b177 absolute adhesive characteristics and qualities of the Armoloy are generated. The surface will not chip, flake, crack, peel, or separate from the base metal on the standard ASTM bend tests or g177 conditions of extreme heat or cold. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, astm b177 oxidation astm b177 specified. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Armoloy deposits a crack-free satin matt finish of Steel substrates shall conform to aztm hardness, hydrogen embrittlement, and surface oxidation characteristics, and quality. Specified chromium electrodeposits on ferrous surfaces are defined in Specification B Referenced Documents purchase separately The documents listed astm b177 are referenced within the subject standard but are not provided as part of the standard.
The Armoloy coating actually becomes integrated with the astm b177 itself. Copper and Copper Alloys.
