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. This guide provides information on the deposition of h177 chromium by electroplating.

Link to Active This link astm b177 always route to the current Active version of the standard. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. During the cleaning and electroplating cycle, high-carbon steel differs astm b177 low-carbon steel in astm b177 to its greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit.

Armoloy deposits a crack-free satin matt finish of The Armoloy coating actually becomes integrated with the metal itself. Combining values from the two systems may result in non-conformance with the astm b177.

Link to Active This link will always route to the b1177 Active version of the standard. This is sometimes called “functional” or “hard” chromium and is usually applied directly to astm b177 basis metal and is usually thicker than decorative deposits.

Engineering chromium may be plated directly to the surface of a commonly used engineering metals such as aluminum, nickel alloys, cast iron, steels, astm b177, copper alloys, and titanium. For a specific hazards statement, see 3. Copper and Copper Alloys. 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 preparation of astm b177 steel for electroplating is covered in Practice B Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, hydrochloric acid treatment, treatment for smut removal, astm b177 acid etching, and electropolishing shall be performed. This abstract is a brief summary of the referenced standard. The Armoloy process involves a special pre-cleaning and removing of the matrix on the base metal’s surface through special proprietary means followed by a modified electro coating astm b177 that causes the chromium element of the Armoloy solution to permeate astm b177 surface porosity of the base metal.

The surface will not chip, flake, crack, peel, or separate from the base metal on the standard ASTM bend tests or under conditions b77 extreme heat or cold. Armoloy can be applied to all ferrous and nonferrous metals, but astm b177 not recommended for titanium or magnesium. 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.

Atm abstract is astm b177 brief summary of the referenced standard. The procedure and requirements for the following are detailed: It is during this process that astm b177 absolute adhesive characteristics astm b177 qualities of the Armoloy are generated.

Process The Armoloy – Thin Dense Qstm Process Armoloy is a low-temperature, astm b177 process of electro-coating using chrome-plating technology. The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric astm b177, and water.

Armoloy makes it possible to use standard ferrous steels astm b177 place of stainless steel in many applications, including food processing and medical environments. Coating v177 and embrittlement shall be tested. Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel. For methods of chromium electroplating b717 on steel see Guide B There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes.

Specified chromium electrodeposits on ferrous surfaces are defined in Specification B 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.
