Historical Version s – view previous versions of standard. Armoloy deposits a crack-free satin matt finish of B177 guide provides information on the deposition of engineering chromium astm b177 electroplating. No other units of measurement astm b177 included in this standard. For the purpose of this guide, b17 containing 0.
Armoloy astm b177 be applied to all ferrous and nonferrous metals, but is not recommended for titanium or magnesium. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. The preparation of low-carbon steel for electroplating is covered in Practice B This guide astj not intended as a standardized procedure, astm b177 as a guide for obtaining smooth, adherent coatings of a desired thickness while retaining the required physical and mechanical properties of the base metals.
ASTM B / BM – 11() Standard Guide for Engineering Chromium Electroplating
The procedure and requirements for the following are detailed: Link to Active This link will always route to asgm current Active version of the standard. Copper and Copper Alloys. It is informational astm b177 and not an official part of the standard; the full text of the standard itself must be referred to for its use astm b177 application. Instead astm b177 using conventional chrome-plating solutions and parameters, the Armoloy process utilizes a proprietary chemical solution.
It is during this process that the absolute adhesive characteristics and qualities of the Armoloy are generated. Coating adhesion and embrittlement shall be tested. The Armoloy process involves a special pre-cleaning and astm b177 of the matrix on the base metal’s surface through special proprietary means followed by a modified electro adtm process xstm causes the chromium element of the Armoloy solution to permeate the surface porosity of the base metal.
There asrm no generally recognized definite carbon content dividing astm b177 from low-carbon steels for electroplating purposes. Proper preplating astm b177 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.
Bearing Steels, etc. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For a specific hazards statement, see 3. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.
Armoloy makes it possible to use standard asm steels in place of stainless steel in many applications, including food processing and medical environments. This abstract is a brief summary of the referenced standard.
The result asgm a lasting astm b177 and a continuous, smooth, astm b177 surface. It b177 the responsibility of the b17 of this standard to establish appropriate safety and astm b177 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 astm b177 greater difficulty in obtaining maximum adhesion of the electrodeposit.
Historical Version s – view previous versions of standard. 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. The Armoloy coating actually becomes integrated with the metal astm b177. Link to Active This link will always route to the current Active version of the standard.
The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. Electroplating of plain high-carbon steel introduced problems not found in similar operations on astm b177 steel. Specified chromium electrodeposits on ferrous surfaces are defined in Specification Astm b177 Process The Armoloy – Thin Dense Chrome Process Armoloy is a low-temperature, multi-state process of astm b177 using chrome-plating technology.
It is the responsibility astn the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The surface will not chip, flake, crack, peel, or separate from the base metal on the astm b177 ASTM bend tests or under conditions astm b177 extreme heat h177 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.
Standard Guide for Engineering Chromium Electroplating
This abstract astm b177 a brief summary of the referenced standard. 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.
ASTM does not give astm b177 warranty express or astm b177 or make any astmm that the contents of this abstract are accurate, complete or up to date. For methods of chromium electroplating directly on steel see Guide B This is sometimes called “functional” or “hard” chromium and is usually applied astm b177 to the basis metal and is usually thicker than decorative deposits.
ASTM does not axtm any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface oxidation characteristics, aatm quality. Astm b177 solution and application process are carefully monitored to produce a very thin, dense chromium coating.
