技术领域
本发明涉及氧化铝陶瓷生产技术领域，具体为一种铁灰色氧化铝耐磨陶瓷的制备方法。
背景技术
一般而言，只要氧化铝陶瓷的制备原材料中没有掺杂污染，则在高温烧结出来后都呈白色，而在实际生产中，人们根据客户的使用要求，不断研发出不同颜色的氧化铝陶瓷，比较常见的有黑色、红色、蓝色、瓦灰色等。
而在氧化铝陶瓷越来越多地取代金属结构件的材料变化中，尤其是能与金属外观颜色相匹配的铁灰色氧化铝陶瓷，其市场需求越来越大，但由于材料选配、加工细度以及处理方法等方面的偏差，使得铁灰色氧化铝耐磨陶瓷的成品往往存在颜色不均匀、不稳定等问题，影响实用效果。
发明内容
本发明的目的在于提供一种铁灰色氧化铝耐磨陶瓷的制备方法，具备颜色均匀纯正并非常稳定的优点，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种铁灰色氧化铝耐磨陶瓷的制备方法，包括以下步骤：
A、选配基底原料和调色原料；
B、一次球磨及稳定化处理：①将调色原料按比例重量称取，倒入刚玉球磨坛（或内衬为刚玉砖的球磨机）中，加入一定量的刚玉瓷球和纯净水，连续球磨24h，均匀混合并使得细度达标；②将球磨后的料浆装入铝盘中，放入150℃左右的烤箱中烤干水份，再放入1200℃-1250℃的温窑炉中煅烧2h；
C、二次球磨及烧结成型：①将稳定化处理后的调色原料与基底原料共同混磨20h，得到细度达标的铁灰色陶瓷粉体；②将塑形后的坯件置于1600℃-1630℃的氧化气氛中烧结，得到纯正的铁灰色氧化铝耐磨陶瓷。
优选的，所述步骤A中基底原料采用100%白色氧化铝陶瓷原料粉体。
优选的，所述步骤A中调色原料有六种，具体配比如下，
钛白粉0.8%-2.5% 二氧化硅0.3%-1% 二氧化锰0.1%-1%
三氧化二铁0.2%-1% 氧化铬0.1%-1% 氧化钴1.0%-2.0%。
优选的，所述钛白粉、二氧化硅、二氧化锰、三氧化二铁、氧化铬以及氧化钴均需达到化学纯（≥99.5%）以上。
优选的，所述步骤B-①中调色原料:刚玉瓷球:纯净水=1:2:2。
优选的，所述步骤B-①中细度D50应达到1.5μm-1.8μm。
优选的，所述步骤C-①中细度D50应达到1.8μm-2.2μm。
与现有技术相比，本发明的有益效果如下：
通过选配合适的调色原料配方，并在一次球磨后对料浆进行除水、煅烧，使得调色原料的颜色均匀纯正并非常稳定，以及通过保证各阶段产品的细度D50，最后得到纯正的与金属颜色高度相仿的铁灰色氧化铝耐磨陶瓷，从而大大提高了该陶瓷产品的实用性能。
