Here you will find up-to-date copies of our certifications and a list of our plating specifications ...

Chrome's hardness rates 68-72 on the Hardness Rockwell C (HRC) scale. Chrome is the hardest metal that is commercially deposited from a bath. In industrial wear applications, hard chrome can be applied in thicknesses ranging from 0.002" to 0.020.". This allows for a wide coverage range of wear needs in a variety of environments.

November 15, 2012 - ASTM International. 5.1 Plating /coating Processes-This test method provides a means by which to detect possible hydrogen embrittlement of steel parts during manufacture by verifying strict controls during production operations such as surface preparation, pretreatments, and plating /coating.

1.1 This standard recommends practice for proper electroplating of metallic coatings on metallic surfaces. 2. PREREQUISTES OF THE BASIS METAL. 2.1 The basis metal should be free from scales and non-metallic inclusions such as slags and refractories, and also from deep pits blisters, cracks, porosity and burrs.

Chrome plating is a prime metal coating. It serves an immense range of needs for an equally vast range of industries; where it remains a reliable choice thanks to Chromium's particular combination of properties. ... (100 µm) or thicker, when extreme wear resistance is required. However, the standard thickness for this chromium plating ranges ...

Functional Hard Chrome plating is widely used throughout the Aerospace industry. To produce functional (thick) hard chrome plating (HCP), chromic acid is used in the plating process. Under applicable government regulatory programs, the hexavalent chromate compound (chromium trioxide) used to produce chromic acid is identified as having an ...

Hard chrome plating measures between 68 and 72 on the Rockwell "C" scale, which is used to determine the indentation hardness of a material. Very hard steels used in tools and quality knife blades typically measure …

This article presents the major uses of hard chromium plating, and focuses on the selection factors, plating solutions, solution and process control, equipment, surface preparation, …

The standard thickness range of decorative chrome plating is between 0.002mm and 0.02mm. Because the decorative chrome layer is so thin, its durability is inferior to that of hard chrome plating. Generally, the decorative chrome plating process begins with electroplating nickel, followed by chrome plating.

Scope. 1.1 This specification covers the requirements for electroplated nickel coatings applied to metal products for engineering applications, for example, for use as a buildup for mismachined or worn parts, for electronic applications, including as underplates in contacts or interconnections, and in certain joining applications.

To ensure that decorative chrome plating meets desired standards, rigorous quality control is necessary. Visual inspection checks for uniformity, brightness, and the absence of defects such as blisters or pits. Thickness testing, using specialized instruments, measures the thickness of the chrome layer, which typically ranges from …

Electrical Properties. Endura ® 500 Series coatings are good thermal and electrical conductors. The electrical resistivity of our 500 Series coatings varies by coating system. Depending on the coating being applied, chrome thickness and density, values may range from 14 to 67 microohm-cm.

Hard-Chrome Plating. Hard-chrome plating is normally described as the application of an electroplated chrome deposit with a thickness of greater than 0.0002 inch. Hard-chrome deposits are normally plated to a thickness of 0.0005–0.01 inch, although in theory almost unlimited thicknesses can be achieved.
