    • The coaxial cable (10) has a metallic signal-transmitting core (12), a dielectric component (14) which is resistant to temperatures of at least about 1000 degrees C., preferably 1000-1100 degrees C., surrounding the core, and a sheath (16) of stainless steel surrounding the dielectric component and core. The outer surface (20) of the sheath (16) has an adherent protective black oxide layer (22) which comprises chromium oxide, preferably in the form of chromic oxide, with essentially the remainder of the black oxide layer being iron oxide. The stainless steel sheath (16) preferably has about 18-20 weight percent of chromium with essentially the remainder being iron. The black oxide layer (22) is formed on the outer surface (20) of the assembled coaxial cable (18), in accordance with the present method, by passing the coaxial cable through a furnace having a hydrogen-free, wet-nitrogen atmosphere, at a temperature of at least about 1000 degrees C., preferably about 1000-1100 degrees C., and for a residence time in the furnace of about two to about five minutes.
    • 同轴电缆(10)具有金属信号传递芯(12),介电部件(14),其耐受围绕芯的至少约1000℃,优选为1000-1100摄氏度的温度,以及 围绕电介质部件和芯的不锈钢护套(16)。 护套(16)的外表面(20)具有粘附保护性黑色氧化物层(22),其包含氧化铬,优选为氧化铬形式,其中黑色氧化物层的其余部分为氧化铁。 不锈钢护套(16)优选具有约18-20重量%的铬,其余基本上为铁。 根据本方法,通过使同轴电缆通过具有无氢,湿氮气氛的炉子,在组装的同轴电缆(18)的外表面(20)上形成黑色氧化物层(22) ,在至少约1000℃,优选约1000-1100℃的温度下,并且在炉中的停留时间为约2至约5分钟。
