一种固体润滑的滚珠轴承及其制备方法
摘要：
本发明公开了一种固体润滑的滚珠轴承，所述滚珠表面具有20-30μm厚度的Ni包覆微米石墨与石墨烯涂层。本发明的复合镀层使得摩擦系数和磨损率同时降低，具有较低的摩擦系数，同时具有比Cr镀层更优良的耐磨性。在各个载荷下，磨损率比基体降低50％以上。
摘要（英）：

The invention discloses a solid lubrication ball bearing and a preparation method thereof. The surface of a ball is provided with a Ni-coated micron graphite and grapheme layer with thickness of 20-30 [mu]m. The composite coating layer enables a friction coefficient and a wear rate to reduce simultaneously, has a lower friction coefficient, and has better abrasion performance than a Cr coating layer. In all loads, the wear rate is reduced by more than 50% compared with a base body.
