    摘要:

    玻璃涂層用作鈦合金鑄錠的高溫保護(hù)涂層,可以同時(shí)解決鑄錠加熱過程中的高溫氧化問題和鍛造過程中的潤(rùn)滑問題,還能起到保溫隔熱的作用,從而降低鈦合金鑄錠的氧化消耗并避免鍛造開裂。介紹了鈦合金鑄錠在加熱和鍛造過程中存在的問題,以及鈦合金鑄錠表面加熱保護(hù)及鍛造潤(rùn)滑用玻璃保護(hù)涂層的研究進(jìn)展,包括涂層的設(shè)計(jì)原則、化學(xué)組成以及制備方法,簡(jiǎn)述了玻璃涂層的抗氧化和潤(rùn)滑機(jī)理以及涂層/基體的高溫界面反應(yīng),并展望了鈦合金鑄錠表面加熱保護(hù)及鍛造潤(rùn)滑用涂層的發(fā)展方向。

    Abstract:

    Ti-based alloy ingots are susceptible to suffering with high temperature oxidation during heat treatment and cracking during forging. So glass-based coatings are used to protect the Ti-based ingots. It can simultaneously increase the oxidation resistance of the ingots and make a positive effect on lubrication during forging. Moreover,the glassbased coating can make a thermal insulation effect due to its low thermal conductivity,which is also beneficial for forging. In this investigation,the development status of the glass-based coatings for Ti-based alloy ingots,including the designing principle,chemical composition,preparation method,mechanisms of high temperature protection and lubrication,interfacial reactions between the coating and the substrate were reviewed. Furthermore,the development direction of the glass-based coating for Ti-based alloy ingots was discussed as well.
