作者在从事耐热钛合金研究过程中,发现TiC在7715C耐热钛合金中与过去在金属陶瓷中不同的现象,TiC非金属化合物非但外形由带棱角与尖角的立方体改变成圆状体而且内部结构有所变化,显微硬度下降。经作者探索性多方面试验,提出金属陶瓷研究的新理论,即非金属化合物可通过特殊技术处理进行变性,通过外形变化及其微观结构的改变从而和基体进行溶合,以复合型的化学性结合代替过去浸润型的物理性结合。 本文以TiC为例介绍TiC在钛合金、高温合金、铌钢合金、镍钛合金中的形貌。着重分析高温金属陶瓷叶片的可能性。 作者认为按新理论进行研制工作,航空发动机中急需的金属陶瓷叶片,航天器上超高温部件,工业上新型耐磨耐蚀零件的制造将有很大发展。
The author in the process of research on heat-resistant titanium alloy, TiC found in the 7715C heat-resistant titanium alloy with the past in the past, different phenomena in the cermet, TiC non-metallic compounds, not only by the angular and angular shape of the cube into a round and The internal structure has changed, decreased microhardness. The author explored many aspects of the experiment, proposed a new theory of cermet research, that non-metallic compounds can be treated by special techniques of denaturation, through changes in shape and microstructure changes and thus the matrix was dissolved in order to compound chemical Combined with the past to replace the infiltration of the physical combination. In this paper, TiC as an example to introduce TiC in titanium, superalloy, niobium steel, nickel-titanium alloy morphology. Focus on the possibility of high-temperature cermet blades. The author believes that according to the new theory of research and development work, the aviation engine in the urgent need of metal ceramic blades, spacecraft on the ultra-high temperature components, industrial new wear-resistant corrosion resistant parts manufacturing will have great development.
