在４５调质钢基体上化学镀ＮｉＢ合金或ＮｉＰ合金镀层．在基础油润滑下，ＮｉＢ合金或ＮｉＰ合金镀层比４５钢耐磨性均提高４１倍，但摩擦系数却分别增加１６３％，２０３５％．在基础油中加入３％的二烷基二硫代磷酸钼（简称ＭｏＤＴＰ）．结果表明，与未加ＭｏＤＴＰ的４５钢相比，ＮｉＢ、ＮｉＰ镀层耐磨性分别提高１２８倍，７倍，摩擦系数分别降低５４％，５１２％，说明ＮｉＢ或ＮｉＰ镀层与ＭｏＤＴＰ有良好的协同效应．

In 45 quenched and tempered steel substrate electroless Ni-B alloy plating or Ni P coating. Under base oil lubrication, the wear resistance of NiB alloy or NiP alloy coating is increased by 41 times than that of 45 steel, but the friction coefficient increases by 163% and 2035% respectively. 3% molybdenum dialkyldithiophosphate (MoDTP) is added to the base oil. The results show that compared with 45 steel without MoDTP, the wear resistance of NiB and NiP coatings increased by 128 and 7 times respectively, the friction coefficient decreased by 54% and 512%, respectively, indicating that NiB Or Ni  P coating and MoDTP have a good synergistic effect.
