Description

抗磨损抗静电复合陶瓷涂层粉末
技术领域
本发明涉及采油工程技术领域，属于一种适用于井下采油螺杆泵的抗磨损抗静电复合陶瓷涂层粉末。
背景技术
针对镀铬层螺杆泵螺杆在三元复合驱采油工程中存在的螺杆泵启动扭矩大、能耗高、螺杆易结垢，抗磨损性能差，检泵周期短、螺杆泵螺杆表面与定子橡胶之间的摩擦易于产生静电等问题，发明了抗磨损抗静电复合陶瓷涂层粉末，利用该粉末制备的复合涂层螺杆泵具有抗磨损、抗静电性能，能够较好地解决常规螺杆的结垢和磨损问题。
发明内容
本发明的目的是发明一种能够较好地解决常规螺杆易结垢，抗磨损性能差，易于产生静电问题的抗磨损抗静电复合陶瓷涂层粉末。
抗磨损抗静电复合陶瓷涂层粉末，它按质量百分比由下列成分组成：73%三氧化二铝、11%二氧化钛、6%二硫化钼、10%氧化锡锑。
本发明抗结垢、耐磨损、抗静电原理：通过在材料表面制备具有较低表面能的三氧化二铝、二氧化钛陶瓷涂层为基体，掺杂二硫化钼和纳米氧化锡锑利用等离子喷涂的方式来降低固体材料表面能。由于二硫化钼的抗磨损主导作用和纳米氧化锡锑的抗静电辅助作用，使得复合涂层抗磨损、抗静电综合性能较好。
本发明与已有技术相比具有以下优点：
本发明得到的抗磨损、抗静电复合陶瓷涂层粉末具有良好的抗磨损、抗结垢、抗腐蚀和抗静电性能，制备的复合涂层螺杆泵表现出优良的抗磨损、抗静电性能，较好解决了常规螺杆的结垢和磨损问题。
具体实施方式：下面结合实施例对本发明作进一步详述，抗磨损抗静电复合陶瓷涂层粉末，它按质量百分比由下列成分组成：73%三氧化二铝、11%二氧化钛、6%二硫化钼、10%氧化锡锑。
本发明的具体制备步骤如下：
a、采用烧结破碎法制备纳米级氧化锡锑导电粉末。将质量分数90%的二氧化锡和10%的三氧化二锑粉末装入陶瓷坩埚中进行机械研磨混合，并放置于高温烧结炉烧结，烧结温度900℃，烧结时间4h。烧结后，经过8h球磨后制成氧化锡锑纳米粉末。
b、采用湿混干燥法制备复合涂层用的等离子喷涂粉末。混粉方式采用机械湿混法，首为先将质量分数73%三氧化二铝、11%二氧化钛、6%二硫化钼、10%氧化锡锑进行混合，然后将混合粉体装入球罐中，加入陶瓷磨球，再加入浓度为99.7%的乙醇作为混料介质，最后将球罐放置在旋转机械上，以200r/min的转速混粉2h，保证粉体能够均匀混合。混粉后将复合粉体进行自然干燥24h，最后放置在200℃的烘箱中干燥24h。
c、用200目筛网分离磨球与粉体。机械混粉并经过自然干燥，让粉体内的乙醇和水分充分蒸发后，取出粉体，并选用200目筛网分离磨球与粉体。然后将分离所得粉体重新放入200℃烘箱中干燥 24h以上，粉体恢复到原始颜色时，方可取出备用，即为所制备的抗磨损抗静电复合陶瓷涂层粉末。此时，所得干燥粉体的粒径大多在75μm以下，完全符合等离子喷涂粉体对粒径的要求。
