摘要： The present invention relates to techniques for lowering friction between moving surfaces of, for example, an internal combustion engine. Friction reduction is achieved by adding texture modifications to surfaces that come in contact with each other. Texture modifications that reduce friction in accordance with the present invention include dimples of varying geometries and depths ion the surfaces of components. The present invention also relates to the fabrication technique for applying the textures to the surfaces. In another embodiment, the patterned soft mask is applied onto a large surface (flat or curved including cylindrical rollers surfaces) to be followed by electrochemical etching to imprint the textures onto the component. And, in another embodiment, a diamond-like-carbon (DLC) film may be applied to the turbine component to also reduce friction.

摘要翻译： 本发明涉及用于降低例如内燃机的移动表面之间的摩擦的技术。 通过将纹理修改添加到彼此接触的表面来实现摩擦减少。 根据本发明减少摩擦的纹理修改包括不同几何形状和深度离开组件表面的凹坑。 本发明还涉及用于将纹理应用于表面的制造技术。 在另一个实施例中，将图案化的软掩模施加到大的表面（平坦或弯曲的包括圆柱形辊表面）上，随后进行电化学蚀刻以将纹理压印到部件上。 而且，在另一个实施例中，可以将类金刚石（DLC）膜施加到涡轮机部件上以减少摩擦。
