Abstract

The friction-enhancing performance of Ni-P/diamond composite coating critically depends on diamond particle bonding strength and uniform distribution. Herein, a metastable Ni-P/diamond coating featuring high bond strength and uniform diamond distribution was successfully developed. The current study reveals the regulation of the bond strength and distribution density of diamond particles in Ni-P/diamond composite coating, as well as the regulation of the microstructure and properties of the composite coating. The main phases of the metastable Ni-P/diamond composite coating were amorphous, diamond and Ni. The Ni-P/diamond composite coating has diamond particles embedded in a size of 1/2–2/3 of their particle size, and the surface distribution density of diamond particles was 25 %. The static coefficient of friction of the Ni-P/diamond composite coating was 0.58. The as-prepared friction-enhancing spacer samples were run in a 560 kW engine for 500 h and no delamination of diamond particles from the Ni-P/diamond composite coating was observed.

高金刚石颗粒结合强度化学镀Ni-P/金刚石复合涂层的显微组织和增摩擦性能

Ni-P/金刚石复合涂层的增摩性能主要取决于金刚石颗粒的结合强度和均匀分布。成功制备了一种结合强度高、金刚石分布均匀的亚稳态Ni-P/金刚石涂层。本研究揭示了Ni-P/金刚石复合涂层中金刚石颗粒的结合强度和分布密度的变化规律，以及复合涂层的显微组织和性能的变化规律。亚稳Ni- p /金刚石复合镀层的主要相为非晶、金刚石和Ni。Ni-P/金刚石复合镀层中金刚石颗粒的嵌套尺寸为其粒径的1/2 ~ 2/3，金刚石颗粒的表面分布密度为25%。Ni-P/金刚石复合涂层的静摩擦系数为0.58。制备的摩擦增强隔离剂样品在560 kW发动机中运行了500 h，未观察到Ni-P/金刚石复合涂层中金刚石颗粒的分层现象。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
