Preparation method of low-cost aluminum oxide and titanium oxide composite powder
The invention discloses a preparation method of low-cost aluminum oxide and titanium oxide composite powder, the aluminum oxide and titanium oxide composite powder is prepared from the following components in parts by weight: 30-400 parts of natural rutile and 600-970 parts of fused white corundum, and the preparation method comprises the following steps: S1, putting the raw materials, namely thefused white corundum and the natural rutile, into a mixer at room temperature, and mixing for 30-300 minutes; S2, putting the mixed raw materials into an electric arc furnace, and electrifying to completely melt the raw materials; S3, crushing the cooled frit into particles with the particle size of 1-3 mm by using a crusher; S4, sending the crushed particles into an airflow crushing and grading device, and crushing and grading to obtain powder with a particle size suitable for plasma spraying; and S5, removing free iron brought by the crusher in the powder through a magnetic separator to obtain finished powder. The composite powder prepared through the method is low in production cost, good in product quality and large in production capacity, the prepared composite coating is good in weather resistance, high in bonding strength and compact, and a foundation is laid for application of plasma spraying in a larger range.
本发明公开了一种低成本氧化铝氧化钛复合粉的制备方法，该氧化铝氧化钛复合粉末由以下成分构成，以份量计：天然金红石30‑400份、电熔白刚玉600‑970份，包括以下步骤：S1、室温下将原料电熔白刚玉和天然金红石投入混料机，混合30‑300分钟；S2、将混合后的原料放入电弧炉中，通电使原料完全熔化；S3、用破碎机将冷却后的熔块破碎至1‑3mm的颗粒；S4、将破碎后的颗粒送入气流粉碎分级中，粉碎并分级出适合等离子喷涂粒径的粉末；S5、用磁选机除去粉末中由破碎机带入的游离铁，得成品粉末。该方法制备的复合粉末生产成本低、产品质量好、生产量大，制备的复合涂层耐候性好，结合强度高，涂层致密，为等离子喷涂在更大范围的应用奠定了基础。
