Standard Guide for Engineering Chromium Electroplating
 N B177/B177M

Annotation

This guide provides information about the deposition of chromium on steel for engineering uses. 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 values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This guide is not intended as a standardized procedure, but as a guide for obtaining smooth, adherent coatings of chromium of a desired thickness while retaining the required physical and mechanical properties of the base metals. Specified chromium electrodeposits on ferrous surfaces are defined in Specification B650.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Типичный гид для технического гальванопокрытия хрома

Это руководство предоставляет информацию о депонировании хрома на стали для технического использования. Это иногда вызывают "функциональным" или "твердым" хромом и обычно применяют непосредственно к базисному металлу и является обычно более толстым, чем декоративные депозиты.
