Preparation method of chromium oxide and titanium oxide composite powder for plasma spraying
The invention discloses chromium oxide and titanium oxide composite powder for plasma spraying. The chromium oxide and titanium oxide composite powder for plasma spraying comprises: 250-550 parts of high titanium slag, 950-1050 parts of chromium sesquioxide, 20-40 parts of a liquid lubricant, 15-35 parts of a coating industrial defoamer, 10-15 parts of a diethyl ether solvent, 3-8 parts of hydroxycellulose, 5-12 parts of ethyl cellulose and 10-15 parts of Arabic gum; wherein the chromium oxide and titanium oxide composite powder is specifically divided into Cr2O3/25%TiO2-CrOx-TiOx composite powder, Cr2O3/40% TiO2-CrOx-TiOx composite powder and Cr2O3/55%TiO2-CrOx-TiOx composite powder by different contents of TiO2. The chromium oxide and titanium oxide composite powder is prepared from thehigh titanium slag instead of titanium dioxide through crushing, mixing, sintering and ball milling; the preparation process is simple, the composite coating prepared from the chromium oxide and titanium oxide composite powder has the characteristics of good weather resistance, high bonding strength, compact coating and the like, and therefore, the production cost is remarkably reduced by replacing titanium dioxide with the high titanium slag.
本发明公开了一种等离子喷涂用氧化铬氧化钛复合粉末，所述等离子喷涂用氧化铬氧化钛复合粉末的配方如下：高钛渣250‑550份、三氧化二铬950‑1050份、液体润滑剂20‑40份、涂料工业消泡剂15‑35份、二乙基醚溶剂10‑15份、羟基纤维素3‑8份、乙基纤维素5‑12份、阿拉伯树胶10‑15份；所述氧化铬氧化钛复合粉末根据TiO2的含量的不同，具体分为Cr2O3·25％TiO2氧化铬氧化钛复合粉末、Cr2O3·40％TiO2氧化铬氧化钛复合粉末和Cr2O3·55％TiO2氧化铬氧化钛复合粉末。本发明采用高钛渣替代钛白粉通过破碎、混合、烧结、球磨制备出氧化铬氧化钛复合粉，制备工艺简单，并且通过该氧化铬氧化钛复合粉制备的复合涂层耐候性好，结合强度高，涂层致密等特点，并且采用高钛渣替代钛白粉显著降低了生产成本。
