技术领域
本发明涉及质量控制技术领域,尤其涉及一种提高金属烤瓷牙上瓷成品率的方法。
背景技术
金属烤瓷牙根据内冠使用材料和制作工艺不同,区分为普通烤瓷、肩台烤瓷、钛合金烤瓷、镀金烤瓷、贵金属烤瓷。其工艺通常包括下列几个步骤。第一步首先制备基底冠,第二步涂覆遮色瓷并烧结,第三步涂覆体瓷进行烧结,最后涂覆透明瓷(釉瓷)并进行烧结,最后经过加工完成成品。这种工艺存在以下缺点,由于金属内冠与陶瓷外冠同时烧结,金属外冠与陶瓷外冠同时冷却,由于金属与陶瓷降温后的收缩率不一致,容易导致烤瓷牙的崩解,从而降低了成品的合格率。

优选的,A2中加热熔化采用高频炉,控制温度在1200-1500℃,并且持续搅拌15min。
优选的,表面处理包括对金属内冠表面进行喷砂以除去其表面附着物,之后对其表面进行抛光之后使用酸液清洗,最后使用清水对金属内冠表面进行冲洗。
优选的,瓷粉的调配过程为:
