Preparation method of Cr2O3 ceramic rod for thermal spraying
The invention discloses a preparation method of a Cr2O3 ceramic rod for thermal spraying, and belongs to the technical field of material science. The preparation method comprises the following steps:weighing ingredients according to the variety formula of a prepared ceramic rod, carrying out ball milling, and drying to obtain red mixed powder; and adding a black material, cellulose, water and liquid paraffin into the powder, mixing and pugging, putting the plastic mud pie into a vacuum extruder, carrying out extrusion molding, heating to carry out rubber discharging treatment, and finally sintering at a certain temperature to obtain the oxide ceramic rod. According to the invention, the Cr2O3 ceramic rod has the advantages of wear resistance, corrosion resistance, high-temperature resistance and oxidation resistance, completely replaces similar imported products, and is a spray coating material with characteristics of low price, stable quality and easy operation; after spraying, the working wear resistance is excellent and is better than that of plasma spraying; and the Cr2O3 ceramic rod is suitable for industries such as aviation, electric power, electric wires and cables, textile chemical fibers, metallurgical steel, petrochemical engineering and the like.
本发明公开了一种热喷涂用CrO陶瓷棒的制备方法，它属于材料科学技术领域。首先按所制备陶瓷棒的种类配方称量配料，球磨后烘干，得到红色混合粉料；然后在粉料中加入黑料和纤维素、水、液体石蜡，进行混料练泥，将可塑泥团放入真空挤出机中，挤出成型，加温进行排胶处理，最后在一定温度下烧结，即为本发明的氧化物陶瓷棒；本发明耐磨损、耐腐蚀、耐高温、抗氧化，完全替代了同类进口产品，且是一种价格低廉、品质稳定、操作容易的喷涂材料；喷涂后的工作耐磨性特佳，比等离子喷涂还要好，适用于航空、电力、电线电缆、纺织化纤、冶金钢铁、石油化工等行业。
