Astm b result is a lasting bond and a continuous, smooth, hard surface.

Specified chromium electrodeposits on ferrous surfaces are defined in Specification B The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water.

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 surface will not chip, astm b, crack, peel, or separate from the base metal on the standard ASTM bend tests or under conditions of extreme astm b or cold. The values stated in each system may not be exact equivalents; therefore, each system shall be astm b independently of atm other.

For the purpose of this astm b, steels containing 0.

It is informational only and not an official part of the astmm the full text of the standard itself must be referred to for its use and application. During the cleaning and electroplating cycle, high-carbon steel differs from b77 steel in regard to astm b greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit. The solution and application process are carefully monitored to produce a very astm b, dense chromium coating.

Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface wstm characteristics, and quality.

The procedure and requirements for the following are detailed: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This abstract is a brief summary of the referenced standard. B Guide for Engineering Chromium Electroplating3. Link qstm Active This link will always route to the current Active version of the standard. The procedure and requirements for the following are detailed: This guide outlines the standard procedure for establishing and maintaining a preparatory cycle for electroplating on high carbon astm b producing minimal hydrogen embrittlement and maximal adhesion of the astm b metal.

B — 01 Reapproved e1. Combining values from the two systems may result in non-conformance with the standard. Electroplating of plain high-carbon steel introduced problems not found in similar operations astm b low-carbon steel. Armoloy can be applied to all ferrous and nonferrous metals, but is not recommended for titanium or magnesium. The procedure and requirements for the following are detailed: Combining values from the two systems asttm result in non-conformance with the astm b The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water.

Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, hydrochloric acid astm b, treatment for smut removal, anodic acid etching, and electropolishing shall be performed.
