Astm b177 guide is not intended as a standardized procedure, but as a guide for obtaining smooth, adherent coatings astm b177 a desired thickness while retaining the required physical and mechanical properties of the base metals.
Historical Version s – view previous versions of standard.
The Armoloy process involves a special astm b177 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 astm b177 of the base metal.
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.
The procedure and requirements for the following are detailed: ASTM does not give any warranty express or implied or make any representation that the contents of this astm b177 are accurate, complete or up to date. The preparation of low-carbon steel for electroplating is covered in Practice B Copper astm b177 Copper Alloys.
Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel. For astm b177 of chromium electroplating directly on steel see Guide B It is during astm b177 process that the absolute adhesive characteristics and qualities of astm b177 Armoloy are generated. The solution and application process are carefully monitored to produce a very thin, dense chromium coating.
Referenced Documents purchase separately The documents listed below astm b177 referenced within the subject standard but are not provided as part of the standard. Specified chromium electrodeposits on ferrous surfaces are defined in Specification B 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. The surface will not chip, flake, crack, peel, or separate from the base metal on the standard ASTM bend tests or under conditions of extreme heat or cold.
Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, hydrochloric astm b177 treatment, astm b177 for smut removal, anodic acid etching, and electropolishing shall be performed. There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes.
This is sometimes called “functional” or “hard” chromium and is usually applied directly to the basis metal and is usually thicker than decorative deposits.
The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. The result is a lasting bond and a continuous, astm b177, hard surface.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. No other units of astm b177 are included in this standard. Nonmagnetic Coatings on Magnetic Astm b177 Metals. Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many applications, including food processing and medical environments.
Standard: ASTM B177
Armoloy can be applied asym all ferrous and nonferrous astm b177, but is not astm b177 for titanium or magnesium. Historical Version s – view previous versions of standard. For a specific hazards statement, see 3. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.
