和玻璃封接用的鉻鐵合金是含鉻28%的鉻鐵合金，又稱做高鉻鋼或28號膨脹合金。合金中由于加入了鉻，使膨脹系數(shù)降低，因此可與軟玻璃進行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點溫度的全部范圍內(nèi)將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。這種合金在封接前需在濕氫中加熱到950℃，使表面形成灰綠色的、薄而致密的CrO3及Fe2O3的氧化層，這種氧化層能很好地溶入玻璃并形成草綠色或褐綠色的封接面。這種合金的特點是，由于含鉻量大于28%，因而其相變點特別高。一般顯像管的第二陽極引線帽及彩色顯像管中屏上固定蔭罩框架的錐頭。圓掃描示波管的偏轉(zhuǎn)電極針等，以及盤形芯柱的管針，均是由高鉻鋼制的。過去當(dāng)顯像管玻璃錐體的壓制工藝未解決時，曾用高鉻鋼作成金屬錐體，再和玻璃屏進行封接，這在一些老式顯像管中還可看到。然而必須注意，當(dāng)加熱到800-1200℃以上時，將產(chǎn)生奧斯丁體鐵，這種奧斯丁體的膨脹系數(shù)要比鐵氧體的鉻鐵合金大得多，并且在較低溫度時，仍能穩(wěn)定地保存在合金中，在這種情況下，將使膨脹系數(shù)改變，因而就會出現(xiàn)膨脹系數(shù)特性曲線不正常的危險，而使材料不適合和玻璃封接。因此，鐵氧體的鉻鐵合金無論是在冶煉生產(chǎn)中或是在使用中，對于奧斯丁體的出現(xiàn)，必須給予很大的注意。<br /> 鉻鐵合金沒有氧化的危險，所產(chǎn)生的綠到鼠灰色的氧化鉻及氧化鐵表面層，是非常牢固地附著在合金絲上，并且在封接過程中還可防止進一步的氧化。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305038193.jpg"
