Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. In current work, we propose a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. In step 1 of this method, one face of the mold was micro-textured using a micro-casting method, in step 2 the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. In step 3, the filled mold was placed in a hot press for a 2-h hot sintering process, and in step 4, the final textured bulk ATSP was completed after cooling down. Subsequently, the micro-textured ATSP bulk material was machined to 6.35 mm diameter pins for pin-on-disk configuration tribologcial studies at different speeds with a contact pressure of 9.1 MPa, under boundary lubrication conditions. Compared with plain untextured flat pins, the micro-textured pins could effectively reduce friction at speeds lower than 1.90 m/s: 14% reduction in average. Scanning electron microscopy was utilized for morphological studies of the micro-textured mold, and micro-textured ATSP samples, before and after the tribological experiments.

表面微纹理已被证明是减少摩擦学应用中摩擦和磨损的有效方法。在当前的工作中，我们提出了一种低成本的热烧结方法，以在高级轴承聚合物材料上应用微织构。在此方法的步骤1中，使用微浇铸方法对模具的一个表面进行微纹理化，在步骤2中，将固化的芳族热固性共聚酯（ATSP）粉末填充到模具中。在步骤3中，将填充的模具放入热压机中进行2小时的热烧结过程，然后在步骤4中，冷却后完成最终的纹理化块状ATSP。随后，将微织构化的ATSP散装材料在边界润滑条件下，以9.1 MPa的接触压力，以不同的速度加工成直径为6.35 mm的销，用于销对盘结构的摩擦学研究。与普通的无纹理扁平销相比，微纹理销可有效降低速度低于1.90 m / s的摩擦：平均降低14％。在摩擦学实验之前和之后，将扫描电子显微镜用于微结构化模具和微结构化ATSP样品的形态研究。
