    摘要:

    主要介紹了鈦合金齒輪在制造過(guò)程中關(guān)鍵的表面處理技術(shù),結(jié)合鈦合金齒輪在運(yùn)行過(guò)程中的受力特征及鈦合金表面無(wú)氫滲碳層的結(jié)構(gòu)特點(diǎn),在其表面制備出TiC+Ti擴(kuò)散層,不僅提高了齒面的耐磨性能,而且也提高了齒面抗沖擊載荷的能力。通過(guò)無(wú)氫滲碳、熱處理及機(jī)械加工工序的有效協(xié)調(diào),制造出的鈦合金齒輪耐磨性能優(yōu)良、抗沖擊振動(dòng)性能良好、噪聲低,已經(jīng)平穩(wěn)運(yùn)行16年。

    Abstract:

    This paper have introduced the key surface treatment technology of titanium alloy wheel gear on the manufacturing process. In view of the mechanics characteristic of titanium alloy wheel gear during the process of operation,as well as the microstructure of the hydrogen-free carburizing coating,the TiC and Ti diffusion layers on the surface of titanium alloy have improved the abrasive resistance and increased the shock resistance of tooth surface. Under the effective coordination of hydrogen-free carburizing,heat treatment and mechanical manufacture,the titanium alloy wheel gear exhibits a very good abrasive resistance,shock resistance,low noise,and has smooth running for 16 years.
