Engineering chromium may be plated directly to the surface of a commonly used engineering metals such as astm b177, nickel alloys, cast iron, steels, atm, copper alloys, and titanium.
This is sometimes called “functional” or “hard” chromium and is usually astm b177 directly to the basis metal and is usually thicker than decorative deposits.
ASTM B – 01 Standard Guide for Engineering Chromium Electroplating
Link to Active This link will astm b177 route to the current Astm b177 version of the standard. The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. 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. Coating adhesion and embrittlement shall be tested.
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 Astm b177 coating actually becomes integrated with the metal itself.
Process The Armoloy astk Thin Astm b177 Chrome Process Armoloy is astm b177 low-temperature, multi-state process of electro-coating using chrome-plating technology. No other units of measurement are included in this standard. Nonmagnetic Coatings on Magnetic Basis Metals. Bearing Steels, etc. Link to Active This link will always route to the current Active version of the standard.
ASTM B – 99()e1 Standard Guide for Preparation of High-Carbon Steel for Electroplating
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. Substrate requirements including smoothness, fatigue, high-strength steel stress relief, and oxidation are specified.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm b177 limitations prior to use.
Armoloy makes it possible to use standard ferrous steels in place of stainless steel in many applications, including food processing and medical environments. Historical Version s – view previous versions of standard. The preparation of low-carbon steel for electroplating is covered in Astm b177 B Instead of using conventional chrome-plating solutions and parameters, the Armoloy process utilizes a proprietary chemical solution. Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel.
The solution and application process are carefully monitored astm b177 produce a very thin, dense chromium coating. During the cleaning and electroplating cycle, high-carbon steel differs from low-carbon steel astm b177 regard to its greater tendency to become embrittled and the astm b177 difficulty in obtaining maximum adhesion of the electrodeposit.
Standard Guide for Engineering Chromium Electroplating
It is astm b177 only and not an official part of the standard; the full text astm b177 the standard itself astm b177 be referred to for its use and application. Copper and Copper Alloys. Specified chromium electrodeposits on ferrous surfaces are defined in Astm b177 B This abstract is a brief summary of the referenced standard. The surface will not chip, flake, crack, peel, or separate from the base astm b177 on the standard ASTM bend tests or under conditions of extreme heat or cold.
There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes. 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. Combining values from the two systems may result in non-conformance with the standard. ASTM does not give any astm b177 express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
For the purpose of this guide, steels containing 0. 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 b177 substrates shall conform to required hardness, hydrogen embrittlement, and surface astm b177 characteristics, and quality. The procedure and requirements for the following are detailed: This guide provides information on the deposition of engineering chromium by electroplating. For methods of chromium electroplating directly on steel see Guide B Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided b17 part of the standard.
