在摩擦磨损试验机上对几种添加剂对某型号发动机密封环摩擦副的摩擦学性能影响进行了试验研究，同时考虑了不同润滑油和密封环表面改性的影响．试验表明，万灵霸添加剂能大幅度提高润滑油对密封环摩擦副的减摩和抗磨性能．
The friction and wear testing machine on several additives on the friction performance of a model engine seal ring tribological properties were studied, taking into account the different lubricants and seal ring surface modification. Tests show that Wanlaiba hemp additive can greatly improve the antifriction and antiwear properties of lubricating oil on the sealing ring friction pair.
