Assemblies of TZM alloy with alumina were obtained with a two-step process, much shorter than moly-manganese brazing methods. This new process involves, first, the preoxidation of the alloy in air at 795 °C, followed by hot-pressing in flowing argon, at 1700 °C under 22 MPa. The adherence of the joints, higher than 45 MPa, was explained by two complementary reasons: i) a mechanical contribution, of “tenon and mortise” type and ii) the penetrations of secondary phases (MoO₂ and minor phases coming from alumina additives) into both materials that play the role of nails joining the alloy and the ceramics.

氧化铝与钛-锆-钼合金结合的新方法

TZM合金与氧化铝的组装是通过两步过程完成的，比钼锰钎焊方法要短得多。这种新工艺首先涉及到在795°C的空气中对合金进行预氧化，然后在1700°C的22 MPa下在流动的氩气中进行热压。关节的附着力高于45 MPa的原因有两个互补的原因：i）“榫和榫眼”类型的机械作用，以及ii）次生相的渗透（来自氧化铝添加剂的MoO ₂和次生相）两种材料都起钉子作用，将合金和陶瓷连接起来。
