摘　　要：为了解决常见的密封条表面涂层磨损失效问题,文章通过大量的试验和对密封条表面涂层工艺控制因素的正交试验分析,通过极差分析和方差分析,优化了试验数据。并最终确认了最佳工艺条件和最优的在线控制指标:喷涂温度95℃;喷枪数量为3把;固化温度190℃;固化时间越长越好,但是考虑到生产效率,一般控制在90 s左右。这些数据的取得为在线涂层工艺控制提供了指导。实际生产线的调整表明,改进后的密封条表面涂层喷涂工艺的应用大幅提高了量产密封条表面涂层的质量,为密封条企业零件产品的合格率提升做出了贡献,产生了显著的经济效益。For wear failure problem of seal strip coating, this article analyzes the control factors of seal strip coating spry process, by using orthngonal test based on range analysis and variance analysis, the test dala are optimized. Final nptinmm process conditions and online control factot.~ are defined, including coating temperature of 95℃, 3 spu guns, curing temperature of 190℃, the longer the curing time lasts, the better the curing effeel presents. The curing time lasts within 90s wilh regard to production efficiency. The data give the guideline for online coating process control. The readjuslmen! tbr the production line indicates that the coating quality of seal strip is enhanced by using the improved coating spu process of seal strip, coating spu process upgrades the acceptable rate of seal strip product, which presents a significant economical benefit.
