Preparation method of AT powder for plasma spraying
The invention discloses a preparation method of AT powder for plasma spraying. Aluminum oxide and titanium oxide composite powder is composed of, by weight: 30-400 parts of high titanium slag and 600-970 parts of brown fused alumina. The preparation method comprises the following steps: S1, putting the raw materials, namely the brown fused alumina and the high titanium slag 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 a cooled molten block into particles with the particle size of 1-3 mm by using a crusher; S4, conveying the crushed particles into an airflow crushing and grading device, and crushing and grading to obtain powder with the 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 throughthe method is low in production cost, good in product quality and large in production capacity, a prepared composite coating is good in weather resistance, high in bonding strength and compact, and afoundation is laid for application of plasma spraying in a larger range.
本发明公开了一种等离子喷涂用AT粉制备方法，该氧化铝氧化钛复合粉末由以下成分构成，以份量计：高钛渣30‑400份、棕刚玉600‑970份，包括以下步骤：S1、室温下将原料棕刚玉和高钛渣投入混料机，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。
