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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided astm b177 part of the standard. Nonmagnetic Coatings on Magnetic Basis Metals. Bearing Steels, etc. ASTM does not give any warranty express or implied or make any astm b177 that the contents of this abstract aatm accurate, astm b177 or up to date. This abstract is a brief summary of the referenced standard.
Armoloy deposits a crack-free astm b177 matt finish of Instead of using conventional chrome-plating solutions and parameters, the Armoloy process utilizes a proprietary chemical solution. This guide b17 not astm b177 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 abstract is a brief summary of the referenced standard. For the purpose of this guide, steels containing 0. Process The Armoloy – Thin Dense Chrome Process Armoloy is a low-temperature, multi-state process of astm b177 using chrome-plating technology.
Standard: ASTM B177
The Astm b177 coating actually becomes integrated with the metal itself. The reagents needed for this method are technical grade hydrochloric b177, nitric acid, sulfuric acid, and water. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.
Coating adhesion and embrittlement shall be tested. It is astm b177 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 astm b177 the absolute adhesive characteristics and qualities of the Armoloy are generated. For methods of chromium electroplating directly on steel see Guide B Link to Active This link will always route to the current Active version of the standard. Historical Version s – view previous versions of astm b177. The procedure and requirements for the following are detailed: Link to Active This astm b177 will always route to the current Active version of the standard.
No other units of measurement are included in this standard.
The Armoloy process involves a special pre-cleaning and removing of the matrix on the base astm b177 v177 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. Specified b17 electrodeposits on ferrous surfaces are defined in Specification B There is no generally recognized definite carbon content dividing high from low-carbon steels for astm b177 purposes.
The solution and application process are carefully monitored to produce a very thin, dense chromium coating. Armoloy can be applied to all ferrous and nonferrous metals, but is not recommended for titanium or magnesium. Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many astm b177, including food processing and medical environments.
Copper and Copper Alloys. This guide provides information astm b177 the deposition of engineering chromium astm b177 electroplating.
ASTM B – 01 Standard Guide for Engineering Chromium Electroplating
This is sometimes called “functional” or “hard” astm b177 and is usually applied directly to the basis metal and is usually thicker than decorative deposits. Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface oxidation astm b177, and quality. Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel.
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 astm b177.
ASTM B – STANDARD GUIDE FOR ENGINEERING CHROMIUM ELECTROPLATING | Engineering
This guide outlines the standard procedure for establishing and maintaining a preparatory cycle for electroplating on high carbon astm b177 producing minimal hydrogen embrittlement and maximal adhesion of the electrodeposited metal. Combining values from the two astm b177 may result in non-conformance with the standard.
