A new direct cast-on technology for the construction of telescopic crowns and precision attachments using non-precious alloys is described. Special ceramic hard substances, such as silicides and borides, are used as separating agents for the casting of the secondary structure. The application of the ceramic layers to the primary crown is accomplished with a chemical vapor deposition method. The layer thickness can be controlled and may range between some hundred nanometres and up to a few micrometres. The attainable gaps between primary and secondary casting range between 1 and 8 microns after separating and finishing.
描述了一种使用非贵金属合金制造套筒冠和精密附件的新型直接铸造技术。特殊的陶瓷硬质物质,如硅化物和硼化物,用作二级结构铸造的分离剂。通过化学气相沉积法将陶瓷层应用于初级冠。层厚度可以控制,范围在几百纳米到几微米之间。分离和精加工后,初级和次级铸件之间可达到的间隙在1至8微米之间。
