一种耐老化复合涂层内燃机用活塞环的制备方法
技术领域
本发明涉及一种活塞环的制备方法,尤其涉及一种耐老化复合涂层内燃机用活塞环的制备方法。
背景技术
活塞环是内燃发动机的关键部件之一,是具有一定弹性的开口环,分为气环和油环,起着密封高温高压燃气、调整气缸壁润滑油膜、传递活塞热量和支撑活塞的作用。活塞环的运动工况复杂,且经常处于恶劣的工作环境中,需要具有良好的耐磨性、耐蚀性和力学性能。随着发动机向高效率、高载荷、高速度及高寿命的方向发展,对活塞环的耐久性和可靠性也提出了更高的要求。
现在的活塞环材料大多数是球墨铸铁和钢材,其耐磨性、耐损伤性较差,因此需要进行表面处理。目前的表面处理技术主要有镀铬、氮化、PVD与CVD镀膜、喷钼、喷涂陶瓷层等。CN201310116281采用大气等离子技术在活塞环表面喷涂陶瓷复合涂层,从而提高了活塞环的耐磨性。然而,这种方法存在涂层与基体结合强度不够,容易发生剥落的问题,在实际应用中需要改进。
发明内容
本发明目的就是为了弥补已有技术的缺陷,提供一种高耐磨、高耐损伤、同时涂层与基体结合强度高、不易发生涂层剥落、使用寿命长的耐老化复合涂层内燃机用活塞环的制备方法。

(2)准备涂层材料,所述涂层材料由下述重量份的原料制得:0.3-0.5%聚乙烯醇溶液30-40,20-50μm氮化铝5-10,20-50μm氧化锆3-5,硅烷偶联剂KH-560 0.3-0.5,钛粉2-4,铜粉1-2,钛酸钾晶须0.5-1,按重量称取上述原料,先将氮化铝、氧化锆与聚乙烯醇溶液混合均匀、喷雾干燥后惰性条件下400-450℃热处理1-2h,然后与钛粉、铜粉混合后在惰性条件下球磨至20-60μm,最后加入其余原料高速混合0.5-1h,即得涂层材料,其中喷雾干燥入口温度为185-195℃,出口温度为100-110℃;
(3)制备活塞环成品,将(2)中的涂层材料采用大气等离子喷涂技术喷涂于(1)中的活塞环基体表面形成厚度为200-500μm涂层,即得耐老化复合涂层内燃机用活塞环。
