摘要

金刚石止推轴承的摩擦副材料，要求聚晶金刚石压片（PDC）具有显著的耐热性、耐磨性和表面润滑性能。本研究以屎壳郎为灵感，通过激光加工和去钴处理制备了去钴纹理PDC （CRT-PDC）。在模拟金刚石止推轴承的井下轴向载荷和转速作用下，研究了复合PDC的摩擦学性能，并与单独去钴和单独表面织构的复合PDC进行了对比。试验结果表明，CRT-PDC的摩擦学性能能够很好地适应金刚石止推轴承的使用条件，为提高金刚石轴承的使用寿命提供了一种新的补救措施。

Cobalt-removed polycrystalline diamond compact with bioinspired texture: Synergistic tribological performance enhancement for diamond thrust bearings

Regarding the friction pair material for diamond thrust bearings, polycrystalline diamond compact (PDC) is required to exhibit pronounced heat resistance, abrasion resistance and surface lubricating capabilities. In the present research, a cobalt- removed textured PDC (CRT-PDC) inspired by the dung beetle was fabricated by laser processing and cobalt removal treatment. Under the simulated downhole axial load and rotational speed of diamond thrust bearings, the tribological behaviors of the fabricated PDC were examined and a parallel comparison was drawn with those of PDC with sole cobalt removal or exclusive surface texturing. The test results showed that the CRT-PDC exhibits tribological properties that are optimally adapted to the operational conditions of diamond thrust bearings, thereby proffering a novel remedy for augmenting the service life of diamond bearings.

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
