1.1 本指南旨在帮助建立和维护高碳钢电镀的准备周期( 注1 )使电沉积金属的氢脆最小，附着力最大。在本指南中，含0.35的钢 % 碳含量或更多的钢和表面硬化低碳钢被定义为高碳钢。电镀用高碳钢和低碳钢之间没有公认的明确碳含量区分。 注1: 介绍了在低碳钢的类似操作中未发现的普通高碳钢电镀问题。在清洁和电镀循环期间，高碳钢与低碳钢的不同之处在于，高碳钢更容易脆化，并且更难获得电镀层的最大附着力。低- 实践中涵盖了电镀用碳钢 B183 . 1.2 本指南不适用于合金钢的电镀。有关直接在钢上电镀铬的方法，请参阅指南 B177 . 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定危险声明，请参阅 3.1 . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This guide is intended as an aid in establishing and maintaining a preparatory cycle for electroplating on high-carbon steel ( Note 1 ) producing a minimum of hydrogen embrittlement and maximum adhesion of the electrodeposited metal. For the purpose of this guide, steels containing 0.35 % of carbon or more, and case-hardened low-carbon steel, are defined as high-carbon steels. There is no generally recognized definite carbon content dividing high from low-carbon steels for electroplating purposes. Note 1: Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel. During the cleaning and electroplating cycle, high-carbon steel differs from low-carbon steel in regard to its greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit. The preparation of low-carbon steel for electroplating is covered in Practice B183 . 1.2 This guide does not apply to the electroplating of alloy steel. For methods of chromium electroplating directly on steel, see Guide B177 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazards statement, see 3.1 . 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
