手术植入物 - 金属材料 - 第12部分:锻造钴铬钼合金

[中文适用范围]： 本文件规定了用于外科植入物的两种锻造钴 28 铬 6 钼合金的要求。 这些特性特别适用于锻制棒材、棒材和线材。 注 1：从该合金制成的成品中获得的样品的机械性能可能与本文件中规定的不同。 注 2：该合金的高碳含量产生了含有显着碳化物分布的结构。 这可以在棒的生产中或在随后的热机械加工中进行调整以生产最终装置。 最终设备中的碳化物分布不包含在本文件中。 [外文原描述]： This document specifies the requirements for two wrought cobalt 28-chromium 6-molybdenum alloys used for surgical implants. The properties apply specifically to wrought bar, rod and wire. NOTE 1 The mechanical properties of a sample obtained from a finished product made of this alloy can differ from those specified in this document. NOTE 2 The high carbon content of this alloy produces a structure containing a significant carbide distribution. This can be adjusted either in the production of the bar or in subsequent thermomechanical processing to produce the final device. Carbide distribution in the final device is not included as part of this document.
