本工作是研究固体薄膜润滑剂应用于要求润滑的滑动或旋转零件表面的方法。靠离子镀和在各种温度的连续退火在钢上制备Cu/Sn双金属镀层,讨论镀层的组成、硬度、摩擦和抗粘结性质。镀层的表面[Rs=0.5,Rs/Sn薄膜的厚度比率:(Sn薄膜的厚度)/(双层Sn/Cu薄膜的总厚度)]在300℃以下退火由η-Cu_6Sn_5相组成,当在400℃退火时在全部镀层上从0.2到0.5的所有Rs值是产生ε-Cu_3Sn相。在各种温度退火的双金属镀层的摩擦系数比离子镀的或未镀的Cu或Sn样品低得多。此外,镀层在干摩擦条件下有优越的抗粘结性质。
This work is to study the application of solid film lubricant on the surface of sliding or rotating parts requiring lubrication. Cu / Sn bimetallic coatings were prepared on steel by ion plating and continuous annealing at various temperatures to discuss the composition, hardness, friction and anti-adhesion properties of the coatings. [Rs = 0.5, Thickness Ratio of Rs / Sn Thin Film: (Thickness of Sn Thin Film) / (Total Thickness of Double Sn / Cu Thin Film)] The surface of the coating layer was annealed at 300 ° C. or less with a composition of η-Cu_6Sn_5 phase, All annealed Rs values from 0.2 to 0.5 over the entire coating yield the ε-Cu_3Sn phase. The bimetallic coatings annealed at various temperatures have a much lower coefficient of friction than either ion-plated or un-plated Cu or Sn samples. In addition, the coating has superior anti-blocking properties under dry friction conditions.
